Write multiple metadata values via WebDAV

Hi All,
When we try to write KM-properties with WebDAV.
At the moment writing of properties with simple values is working (e.g. document_year --> 2009), but properties with multiple values (e.g. document_country --> DE, EN, FR) not.
Even when we try to read such values and write them unchanged back to the KM, the KM can't use them any more. Instead of showing the properties in the portal, I get the XML code displayed.
Please Help !!

Or, actually, the response for the PROPFIND, and the request body for PROPPATCH.
(is this a custom WebDAV client?)

Changing multiple cell values via pop-up?

hi.
back again
I'm reworking my cost estimate sheet and would like to know if the following idea is possible: [the .numbers will probably explain it better than i can]
http://web.me.com/jeffhammond/numbersQ_2.numbers
generally, i will enter unit costs on a job to job basis (or at least spot check pricing per region).. i'll still do this but i'd like to keep the editing off the estimate table and do it on a separate table.. the main reason is that i'll often have to change every cost due to the material requirements.. same dimensions etc but certain jobs require weather resistant materials/hardware.. i'd like to simply switch the type of job on the estimate sheet and bring the correct pricing in.
I'm also not positive that all materials on the estimate sheet will maintain their current position.. i may have to special order something (6x6 -24' ?) for whatever reason in which i'd usually insert it under the post materials.. if need be, i guess i could add any special order materials to a designated are so as not to change any cells.
fwiw, a complete material list will often have over 100 separate item types being ordered from multiple sources.. my main material list has around 450 individual items that i can choose from/order.. (but i have a nice little setup in place to filter only ordered materials and for obtaining individual pdfs per outlet which includes only items they sell).. point being, my example .numbers wouldn't be worth implementing something like this but the real list is more intense.
any ideas?
thanks
jeff

Hi Jeff,
I'm beginning to develop a strong dislike for this forum's new interface!!
But that's not your fault.
The tables below use a VLOOKUP formula to retrieve the prices from the Current Pricing, and an IF statement in E1 to determine which column the prices are fetched from.
The added column isn't necessary; it was just simpler t do that than to go through the hassle of re-merging the single cell in Row 1. With a change of the cell reference in the VLOOKUP formula, the first formula can be placed anywhere convenient.
In E1:
=IF(LEFT(A1,1)="I",2,3)
The result of this formula tells VLOOKUP to return the results from column 2 or 3 of the Current Pricing table, depending on the first letter of the text in A1 being an "I".
In C3 and Filled Down:
=IF(B>0,VLOOKUP(A,Current Pricing :: $A:$C,$E$1,FALSE),"")
IF is used to return a null string unless there is a value greater than zero in column B.
Looks for the item listed in Column A and returns the value from the row where that item is found and the column specified in E1.
The error triangle in C9 is a "VLOOKUP cannot find.." error cause by the value '3” screws (25lb box)' not being found in column A of Current Pricing.
The error triangle in D9 is "There is an error in C9".
Regard,
Barry
PS: The line at the beginning?
I had complete all but the last line of a previous version of this post, and was deleting the '3" screws..." bit which had pasted as a single cell unnamed table, when the software bumped me back to the previous thread in this community. Not the first time this has happened, and in this case, as in the ones before, there appeared to be no route back to my partly completed message. So it was start over time. (/rant)

EFS Encrypted Files over home workgroup network via WebDAV avoiding Active Directory fixing Access Denied errors

This is for information to help others
KEYWORDS:
- Sharing EFS encrypted files over a personal lan wlan wifi ap network
- Access denied on create new file / new fold on encrypted EFS network file share remote mapped folder
- transfer encryption keys / certificates
- set trusted delegation for user + computer for EFS encrypted files via
Kerberos
- Windows Active Directory vs network file share
- Setting up WinDAV server on Windows 7 Pro / Ultimate
It has been a long painful road to discover this information.
I hope sharing it helps you.
Using EFS on Windows 7 pro / ultimate is easy and works great. See
here and
here
So too is opening + editing encrypted files over a peer-to-peer Windows 7 network.
HOWEVER, creating a new file / new folder over a peer-to-peer Windows 7 network
won't work (unless you follow below steps).
Typically, it is only discovered as an issue when a home user wants to use synchronisation software between their home computers which happens to have a few folders encrypted using windows EFS. I had this issue trying to use GoodSync.
Typically an "Access Denied" error messages is thrown when a \\clientpc tries to create new folder / new file in an encrypted folder on a remote file share \\fileserver.
Why such a EFS drama when a network is involved?
Assume a home peer-to-peer network with 2pc: \\fileserver and \\clientpc
When a \\clientpc tries to create a new file or new folder on a \\fileserver (remote computer) it fails. In a terribly simplified explanation it is because the process on \\fileserver that is answering the network requests is a process working for a user on
another machine (\\clientpc) and that \\fileserver process doesn't have access to an encryption certificate (as it isn't a user). Active Directory gets around this by using kerberos so the process can impersonate a \\fileserver user and then use their certificate
(on behalf of the clienpc's data request).
This behaviour is confusing, as a \\clientpc can open or edit an existing efs encrypted file or folder, just can't create a new file or folder. The reason editing + opening an encrypted file over a network file share is possible is because the encrypted
file / folder already has an encryption certificate, so it is clear which certificate is required to open/edit the file. Creating a new file/folder requires a certificate to be assigned and a process doesn't have a profile or certificates assigned.
Solutions
There are two main approaches to solve this:
 1) SOLVE by setting up an Active Directory (efs files accessed through file shares)
 EFS operations occur on the computer storing the files.
 EFS files are decrypted then transmitted in plaintext to the client's computer
 This makes use of kerberos to impersonate a local user (and use their certificate for encrypt + decrypt)
 2) SOLVE by setting up WebDAV (efs files accessed through web folders)
 EFS operations occur on the client's local computer
 EFS files remain encrypted during transmission to the client's local computer where it is decrypted
 This avoids active directory domains, roaming or remote user profiles and having to be trusted for delegation.
 BUT it is a pain to set up, and most online WebDAV server setup sources are not for home peer-to-peer networks or contain details on how to setup WebDAV for EFS file provision
 READ BELOW as this does
Create new encrypted file / folder on a network file share - via Active Directory
It is easily possible to sort this out on a domain based (corporate) active directory network. It is well documented. See
here. However, the problem is on a normal Windows 7 install (ie home peer-to-peer) to set up the server as part of an active directory domain is complicated, it is time consuming it is bulky, adds burden to operation of \\fileserver computer
and adds network complexity, and is generally a pain for a home user. Don't. Use a WebDAV.
Although this info is NOT for setting up EFS on an active directory domain [server],
for those interested here is the gist:
Use the Active Directory Users and Computers snap-in to configure delegation options for both users and computers. To trust a computer for delegation, open the computer’s Properties sheet and select Trusted for delegation. To allow a user
account to be delegated, open the user’s Properties sheet. On the Account tab, under Account Options, clear the The account is sensitive and cannot be delegated check box. Do not select The account is trusted for delegation. This property is not used with
EFS.
NB: decrypted data is transmitted over the network in plaintext so reduce risk by enabling IP Security to use Encapsulating Security Payload (ESP)—which will encrypt transmitted data,
Create new encrypted file / folder on a network file share - via WebDAV
For home users it is possible to make it all work.
Even better, the functionality is built into windows (pro + ultimate) so you don't need any external software and it doesn't cost anything. However, there are a few hotfixes you have to apply to make it work (see below).
Setting up a wifi AP (for those less technical):
 a) START ... CMD
 b) type (no quotes): "netsh wlan set hostednetwork mode=allow ssid=MyPersonalWifi key=12345 keyUsage=persistent"
 c) type (no quotes): "netsh wlan start hostednetwork"

 c) put a tick in: "World Wide Web Services" \ "Common HTTP Features" \ "WebDAV Publishing"
 d) put a tick in: "World Wide Web Services" \ "Security" \ "Basic Authentication"

2 Click START and type "Internet Information Services (IIS) Manager"
3 in IIS, on the left under "connections" click your computer, then click "WebDAV Authoring Rules", then click "Open Feature"
 a) on the right side, under Actions, click "Enable WebDAV"
4 in IIS, on the left under "connections" click your computer, then click "Authentication", then click "Open Feature"
 a) on the "Anonymous Authentication" and click "Disable"
 b) on the "Windows Authentication" and click "Enable"
 NB: Some Win 7 will not connect to a webDAV user using Basic Authentication.
 It can be by changing registry key:
 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WebClient\Parameters]
 BasicAuthLevel=2
 c) on the "Windows Authentication" click "Advanced Settings"
 set Extended Protection to "Required"
 NB: Extended protection enhances the windows authentication with 2 security mechanisms to reduce "man in the middle" attacks
5 in IIS, on the left under "connections" click your computer, then click "Authorization Rules", then click "Open Feature"
 a) on the right side, under Actions, click "Add Allow Rule"
 b) set this to "all users". This will control who can view the "Default Site" through a web browser
 NB: It is possible to specify a group (eg Administrators is popular) or a user account. However, if not set to "all users" this will require the specified group/user account to be used for logged in with on the
clientpc.
 NB: Any user account specified here has to exist on the server. It has a bug in that it usernames specified here are not validated on input.

HOTFIX - double escaping
7 in IIS, on the left under "connections" click your computer, then click "Request Filtering", then click "Open Feature"
 a) on the right side, under Actions, click "Edit Feature Settings"
 b) tick the box "Allow double escaping"
 *THIS IS VERY IMPORTANT* if your filenames or foldernames contain characters like "+" or "&"
 These folders will appears blank with no subdirectories, or these files will not be readable unless this is ticked
 This is safe btw. Unchecked (default) it filters out requests that might possibly be misinterpreted by buggy code (eg double decode or build url's via string-concat without proper encoding). But any bug would need to be in IIS basic
file serving and this has been rigorously tested by microsoft, so very unlikely. Its safe to "Allow double escaping".
8 in IIS, on the left under "connections" right click "Default Web Site", then click "Add Virtual Directory"
 a) set the Alias to something sensible eg "D_Drive", set the physical path
 b) it is essential you click "connect as" and set
this to a local user (on fileserver),
 if left as "pass through authentication" a client won't be able to create a new file or folder in an encrypted efs folder (on fileserver)
 NB: the user account selected here must have the required EFS certificates installed.
 See
here and
here
 NB: Sharing the root of a drive as an active directory (eg D:\ as "D_Drive") often can't be opened on clientpcs.
 This is due to windows setting all drive roots as hidden "administrative shares". Grrr.
 The work around is on the \\fileserver create an NTFS symbollic link
 e.g. to share the entire contents of "D:\",
 on fileserver browse to site path (iis default this to c:\inetpub\wwwroot)
 in cmd in this folder create an NTFS symbolic link to "D:\"
 so in cmd type "cd c:\inetpub\wwwroot"
 then in cmd type "mklink /D D_Drive D:\"
 NB: WebDAV will open this using a \\fileserver local user account, so double check local NTFS permissions for the local account (clients will login using)
 NB: If clientpc can see files but gets error on opening them, on clientpc click START, type "Manage Network Passwords", delete any "windows credentials" for the fileserver being used, restart
clientpc
9 in IIS, on the left under "connections" click on "WebDAV Authoring Rules", then click "Open Feature"
 a) click "Add authoring rules". Control access to this folder by selecting "all users" or "specified groups" or "specified users", then control whether they can read/write/source
 b) if some exist review existing allow or deny.
 Take care to not only review the "allow access to" settings
 but also review "permissions" (read/write/source)
 NB: this can be set here for all added virtual directories, or can be set under each virtual directory
10 Open your firewall software and/or your router. Make an exception for port 80 and 443
 a) In Windows Firewall with Advanced Security click Inbound Rules, click New Rule
 choose Port, enter "80, 443" (no speech marks), follow through to completion. Repeat for outbound.
 NB: take care over your choice to untick "Public", this can cause issues if no gateway is specified on the network (ie computer-to-computer with no router). See "Other problems+fixes"
below, specifically "Cant find server due to network location"
 b) Repeat firewall exceptions on each client computer you expect to access the webDAV web folders on
HOTFIX - MAJOR ISSUE - fix KB959439
11 To fully understand this read "WebDAV HOTFIX: RAW DATA TRANSFERS" below
 a) On Windows 7 you need only change one tiny registry value:
 - click START, type "regedit", open link
 -browse to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\MRxDAV\Parameters]
 -on the EDIT menu click NEW, then click DWORD Value
 -Type "DisableEFSOnWebDav" to name it (no speech marks)
 -on the EDIT menu, click MODIFY, type 1, then click OK
 -You MUST now restart this computer for the registry change to take effect.
 b) On Windows Server 2008 / Vista / XP you'll FIRST need to
download Windows6.0-KB959439 here. Then do the above step.
 NB microsoft will ask for your email. They don't care about licence key legality, it is more to keep you updated if they modify that hotfix
12 To test on local machine (eg \\fileserver) and deliberately bypass the firewall.
 a) make sure WebClient Service is running
 (click START, type "services" and open, scroll down to WebClient and check its status)
 b) Open your internet software. Go to address "http://localhost:80" or "http://localhost:80"
 It should show the default "IIS7" image.
 If not, as firewall and port blocking are bypassed (using localhost) it must be a webDAV server setting. Check "Authorization Rules" are set to "Allow All Users"
 c) for one of the "virtual directories" you added (8), add its "alias" onto "http://localhost/"
 e.g. http://localhost/D_drive
 If nothing is listed, check "Directory Browsing" is enabled
13 To test on local machine or a networked client and deliberately try and access through the firewall or port opening of your router.
 a) make sure WebClient Service is running
 (click START, type "services" and open, scroll down to WebClient and check its status)
 b) open your internet software. Go to address "http://<computer>:80" or "http://<computer>:80".
 eg if your server's computer name is "fileserver" go to "http://fileserver:80"
 It should show the default "IIS7" image. If not, check firewall and port blocking.
 Any issue ie if (12) works but (13) doesn't, will indicate a possible firewall issue or router port blocking issue.
 c) for one of the "virtual directories" you added (8), add its "alias" onto "http://<computername>:80/"
 eg if alias is "C_driver" and your server's computer name is "fileserver" go to "http://fileserver:80/C_drive"
 A directory listing of files should appear.
--- ON EACH CLIENT ----
HOTFIX - improve upload + download speeds
14 Click START and type "Internet Options" and open the link
 a) click the "Connections" tab at the top
 b) click the "LAN Settings" button at the bottom right
 c) untick "Automatically detect settings"
HOTFIX - remove 50mb file limit
15 On Windows 7 you need only change one tiny registry value:
 a) click START, type "regedit", open link
 b) browse to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WebClient\Parameters]
 c) click on "FileSizeLimitInBytes"
 d) on the EDIT menu, click MODIFY, type "ffffffff", then click OK (no quotes)
HOTFIX - remove prompt for user+pass on opening an office or pdf document via WebDAV
16 On each clientpc click START, type "Internet Options" and open it
 a) click on "Security" (top) and then "Custom level" (bottom)
 b) scroll right to the bottom and under "User Authentication" select "Automatic logon with current username and password"
 SUCH an easy fix. SUCH an annoying problem on a clientpc
 NB: this is only an issue if the file is opened through windows explorer. If opened through the "open" dialogue of the software itself, it doesn't happen. This is as a WebDAV mapped drive is consdered a "web folder" by windows
explorer.
TEST SETUP
17 On the client use the normal "map network drive"
 e.g. server= "http://fileserver:80/C_drive", tick reconnect at logon
 e.g. CMD: net use * "http://fileserver:80/C_drive"
 If it doens't work check "WebDAV Authoring Rules" and check NTFS permissions for these folders. Check that on the filserver the elected impersonation user that the client is logging in with (clientpc
"manage network passwords") has NTFS permissions.
18 Test that EFS is now working over the network
 a) On a clientpc, map network drive to http://fileserver/
 b) navigate to a folder you know on the \\flieserver is encrypted with EFS
 c) create a new folder, create a new file.
 IF it throws an error, check carefully you mapped to the WebDAV and not file share
 i.e. mapped to "http://fileserver" not "\\fileserver"
 Check that on clientpc the required efs certificate is installed. Then check carefully on clientpc what user account you specified during the map drive process. Then check on the \\fileserver this
account exists and has the required EFS certificate installed for use. If necessary, on clientpc click START, type "Manage Network Passwords" and delete the windows credentials currently in the vault.
 d) on clientpc (through a webDAV mapped folder) open an encrypted file, edit it, save it, close it. On the \\fileserver now check that file is readable and not gobble-de-goup
 e) on clientpc copy an encrypted efs file into a folder (a webDAV mapped folder) you know is not encrypted on \\fileserver. Now check on the \\fileserver computer that the file is readable and not gobble-de-goup (ie the
clientpc decrypted it then copied it).
 If this fails, it is likely one in IIS setting on fileserver one of the shared virtual directories is set to: "pass through authentication" when it should be set to "connect as"
 If this is not readable check step (11) and that you restarted the \\fileserver computer.
19 Test that clients don't get the VERY annoying prompt when opening an Office or PDF doc
 a) on clientpc in windows explorer browse to a mapped folder you know is encrypted and open an office file and then PDF.
 If a prompt for user+pass then check hotfix (16)
20 Consider setting up a recycling bin for this mapped drive, so files are sent to recycling bin not permanently deleted
 a) see the last comment at the very bottom of
this page:
Points to consider:
 - NB: WebDAV runs on \\fileserver under a local user account, so double check local NTFS permissions for that local account and adjust file permissions accordingly. If the local account doesn't have permission, the webDAV / web folder share won't
either.
- CONSIDER: IP Security (IPSec) or Secure Sockets Layer (SSL) to protect files during transport.
MORE INFO: HOTFIX: RAW DATA TRANSFERS
More info on step (11) above.
Because files remain encrypted during the file transfer and are decrypted by EFS locally, both uploads to and downloads from Web folders are raw data transfers. This is an advantage as if data is intercepted it is useless. This is a massive disadvantage as
it can cause unexpected results. IT MUST BE FIXED or you could be in deep deep water!
Consider using \\clientpc to access a webfolder on \\fileserver and copying an encrypted EFS file (over the network) to a web folder on \\fileserver that is not encrypted.
Doing this locally would automatically decrypt the file first then copy the decrypted file to the non-encrypted folder.
Doing this over the network to a web folder will copy the raw data, ie skip the decryption stage and result in the encrypted EFS file being raw copied to the non-encrypted folder. When viewed locally this file will not be recognised as encrypted (no encryption
file flag, not green in windows explorer) but it will be un-readable as its contents are still encrypted. It is now not possible to locally read this file. It can only be viewed on the \\clientpc
There is a fix:
 It is implimented above, see (11) above
 Microsoft's support page on this is excellent and short. Read "problem description" of "this microsoft webpage"
Other problems + fixes
PROBLEM: Can't find server due to network location.
 This one took me a long time to track down to "network location".
 Win 7 uses network locations "Home" / "Work" / "Public".
 If no gateway is specified in the IP address, the network is set to '"unidentified" and so receives "Public" settings.
 This is a disaster for remote file share access as typically "network discovery" and "file sharing" are disabled under "Public"
 FIX = either set IP address manually and specify a gateway
 FIX = or force "unidentified" network locations to assume "home" or "work" settings -
read here or
here
 FIX = or change the "Public" "advanced network settings" to turn on "network discovery" and "file sharing" and "Password Protected Sharing". This is safe as it will require a windows
login to gain file access.
PROBLEM: Deleting files on network drive permanently deletes them, there is no recycling bin
 By changing the location of "My Contacts" or similar to the root directory of your mapped drive, it will be added to recycling bin locations
 Read

I really hope this helps people. I hope the keywords + long title give it the best chance of being picked up in web searches.

What probably happens is that processes are using those mounts. And that those processes are not killed before the mounts are unmounted. Is there anything that uses those mounts?

Metadata values not showing in Site Studio layout using Idoc Script

Hi All,
We have a SS layout (secondary) with replaceable regions for showing content that is listed in a primary page dynamic list.
Part of the layout shows contribution elements of Contributor Data File content items, but part of layout also shows metadata values. We use  to show the content item Title with no problems.
However, for some content items, some metadata values are not showing on the layout - specifically a custom metadata field called xFinishDate (which is of type 'Date' in Config Man). The code  simply does not work (nothing is displayed) for some content items, despite definitely having a set FinishDate value. Some other content items show this value fine.
The  value works for ALL items, but the  does not, and there appears to be no difference between the items that it does, and does not work for. They are all CDF, same DocType, same CheckIn profile, etc.
The non-working items are all released and indexed. Their Content Information in Content Server shows complete metadata. I have resubmitted the non-working items for reconversion in Repo Man but no luck.
Is there something I am missing? Any help is greatly appreciated.
Luke.

Actually the default DOC_INFO resultset that is on the page seems to be for the content item being loaded into the secondary layout's replaceable regions. This is why DOC_INFO.dDocTitle gives the results expected.
However, I think I have discovered why the xFinishDate value was not showing. Using sapan's code (and modifying it a bit) I was able to print out all the metadata field names and values for default DOC_INFO resultset.
Using this URL as an example: http://www.bond.edu.au/about-bond/jobs-at-bond/BD3_011217
At the top of page region (replaceable) where the Contributor Data File is loaded into, the DOC_INFO resultset is relevant to the content item that is being loaded into the layout (content ID: BD3_011217 - as per the URL format), which is what we want.
However, throughout the Contributor Data File content, if a link is made using the Site Studio link wizard via FCK Editor (in the above case, it is the position description link, which is a link to a PDF) and the link is 'Link to a file' and the 'Choose Target section' is selected as 'Use default website section metadata', the resulting link looks like "http://www.bond.edu.au/about-bond/jobs-at-bond/BD3_011216". Any references to the DOC_INFO resultset on the page after the instance of this link now use the metadata of the content item referred to in the link, not the original content item. I have dumped out the DOC_INFO fields/values in different parts of the layout to prove this. The linked content item has no xFinishDate value so this is why nothing displays (displaying xFinishDate needs to happen after the link to the position description).
I guess I need to either:
- change the way the link is made to the content item to "Link to the Content Item's URL", but I would prefer not to expose the resulting path e.g. "[!--$HttpRelativeWebRoot--]groups/group-name/@account-name/documents/content-type/content-id.pdf"
- explicitly make a resultset using  with the content ID I know I want and use it instead of the default DOC_INFO one. Is there any other way to make a resultset comprising of a single item's metadata?
9.45 SS_GET_SEARCH_RESULTS
■ Description: This is a wrapper around the regular CS GET_SEARCH_RESULTS
service. It allows some Site Studio features to be specified simply as flags and have
the real query syntax be constructed on the server. It can modify the standard
'SearchResults' resultset to contain an additional column called 'ssUrl' which will
contain the Site Studio-friendly url for all of the search results.
■ Parameters:
– siteId: the unique identifier of the site (required).
– ssLimitScope: True/False, restricting scope to within the site only (optional).
– ssUserSearchText: user-supplied search text (optional).
– ssWebsiteObjectType: object type (optional).
– computeFriendlyUrls: True/False, modify results to include ssUrl (optional).
■ Returns: resultset named ’Search Results’.
■ Security: The user must have at write access to at least one security group on the
content server
Thanks to everyone for their help. Almost there!

Multiple return values (Bug-ID 4222792)

I had exactly the same request for the same 3 reasons: strong type safety and code correctness verification at compile-time, code readability and ease of mantenance, performance.
Here is what Sun replied to me:
Autoboxing and varargs are provided as part of
JSRs 14 and 201
http://jcp.org/en/jsr/detail?id=14
http://jcp.org/en/jsr/detail?id=201
See also:
http://forum.java.sun.com/forum.jsp?forum=316
http://developer.java.sun.com/developer/earlyAccess/adding_generics/index.html
Multiple return values is covered by Bug-ID 4222792
Typically this is done by returning an array.
http://developer.java.sun.com/developer/bugParade/bugs/4222792.html
That's exactly the problem: we dynamically create instances of array objects that would better fit well within the operand stack without stressing the garbage collector with temporary Array object instances (and with their backing store: 2 separate allocations that need to be recycled when it is clearly a pollution that the operand stack would clean up more efficiently)
If you would like to engage in a discussion with the Java Language developers, the Generics forum would be a better place:
http://forum.java.sun.com/forum.jsp?forum=316
I know that (my report was already refering to the JSR for language extension) Generics is not what I was refering to (even if a generic could handle multiple return values, it would still be an allocated Object
instance to pack them, i.e. just less convenient than using a static class for type safety.
The most common case of multiple return values involve values that have known static datatypes and that should be checked with strong typesafety.
The simple case that involves returning two ints then will require at least two object instances and will not solve the garbage collection overhead.
Using a array of variable objects is exactly similar, except that it requires two instances for the components and one instance for the generic array container. Using extra method parameters with Integer, Byte, ... boxing objects is more efficient, but for now the only practical solution (which causes the least pollution in the VM allocator and garbage collector) is to use a custom class to store the return values in a single instance.
This is not natural, and needlessly complexifies many interfaces.
So to avoid this pollution, some solutions are used such as packing two ints into a long and returning a long, depacking the long after return (not quite clean but still much faster at run-time for methods that need to be used with high frequencies within the application. In some case, the only way to cut down the overhead is to inline methods within the caller code, and this does not help code maintenance by splitting the implementation into small methods (something that C++ can do very easily, both because it supports native types parameters by reference, and because it also supports inline methods).
Finally, suppose we don't want to use tricky code, difficult to maintain, then we'll have to use boxing Object types to allow passing arguments by reference. Shamely boxed native types cannot be allocated on the operand stack as local variables, so we need to instanciate these local variables before call, and we loose the capacity to track the cases where these local variables are not really initialized by an effective call to the method that will assign them. This does not help debugging, and is against the concept of a strongly typed language like Java should be:
Java makes lots of efforts to track uninitialized variables, but has no way to determine if an already instanciated Object instance refered in a local variable has effectively received an effective assignment because only the instanciation is kept. A typical code will then need to be written like this:
Integer a = null;
Integer b = null;
if (some condition) {
//call.method(a, b, 0, 1, "dummy input arg");
// the method is supposed to have assigned a value to a and b,
// but can't if a and b have not been instanciated, so we perform:
call.method(a = new Integer(), b = new Integer(), 0, 1, "dummy input
arg");
// we must suppose that the method has modified (not initialized!)
the value
// of a and b instances.
now.use(a.value(), b.value())
// are we sure here that a and b have received a value????
// the code may be detected at run-time (a null exception)
// or completely undetected (the method() above was called but it
// forgot to assign a value to its referenced objects a and b, in which
// case we are calling in fact: now.use(0, 0); with the default values
// or a and b, assigned when they were instanciated)
Very tricky... Hard to debug. It would be much simpler if we just used:
int a;
int b;
if (some condition) {
(a, b) = call.method(0, 1, "dummy input arg");
now.use(a, b);
The compiler would immediately detect the case where a and b are in fact not always initialized (possible use bere initialization), and the first invoked call.method() would not have to check if its arguments are not null, it would not compile if it forgets to return two values in some code path...
There's no need to provide extra boxing objects in the source as well as at run-time, and there's no stress added to the VM allocator or garbage collector simply because return values are only allocated on the perand stack by the caller, directly instanciated within the callee which MUST (checked at compile-time) create such instances by using the return statement to instanciate them, and the caller now just needs to use directly the variables which were referenced before call (here a and b). Clean and mean. And it allows strong typechecking as well (so this is a real help for programmers.
Note that the signature of the method() above is:
class call {
(int, int) method(int, int, String) { ... }
id est:
class "call", member name "method", member type "(IILjava.lang.string;)II"
This last signature means that the method can only be called by returning the value into a pair of variables of type int, or using the return value as a pair of actual arguments for another method call such as:
call.method(call.method("dummy input arg"), "other dummy input arg")
This is strongly typed and convenient to write and debug and very efficient at run-time...

Can anyone give me some real-world examples where
multiple return values aren't better captured in a
class that logically groups those values? I can of
course give hundreds of examples for why it's better
to capture method arguments as multiple values instead
of as one "logical object", but whenever I've hankered
for multiple return values, I end up rethinking my
strategy and rewriting my code to be better Object
Oriented.I'd personally say you're usually right. There's almost always a O-O way of avoiding the situation.
Sometimes though, you really do just want to return "two ints" from a function. There's no logical object you can think of to put them in. So you end up polluting the namespace:
public class MyUsefulClass {
public TwoInts calculateSomething(int a, int b, int c) {
public static class TwoInts {
    //now, do I use two public int fields here, making it
    //in essence a struct?
   //or do I make my two ints private & final, which
   //requires a constructor & two getters?
//and while I'm at it, is it worth implementing
//equals(), how about hashCode()? clone()?
//readResolve() ?
}The answer to most of the questions for something as simple as "TwoInts" is usually "no: its not worth implementing those methods", but I still have to think about them.
More to the point, the TwoInts class looks so ugly polluting the top level namespace like that, MyUsefulClass.TwoInts is public, that I don't think I've ever actually created that class. I always find some way to avoid it, even if the workaround is just as ugly.
For myself, I'd like to see some simple pass-by-value "Tuple" type. My fear is it'd be abused as a way for lazy programmers to avoid creating objects when they should have a logical type for readability & maintainability.
Anyone who has maintained code where someone has passed in all their arguments as (mutable!) Maps, Collections and/or Arrays and "returned" values by mutating those structures knows what a nightmare it can be. Which I suppose is an argument that cuts both ways: on the one hand you can say: "why add Tuples which would be another easy thing to abuse", on the other: "why not add Tuples, given Arrays and the Collections framework already allow bad programmers to produce unmainable mush. One more feature isn't going to make a difference either way".
Ho hum.

How do I graph multiple bit values on one time axis?

I want to graph multiple bit values, all of which will change back and forth from 0 to 1, on the same time axis, but I don't want any visual overlap between the different bit value traces. Now I could do this by graphing bit one as either 0 or 1, bit 2 as 2 or 3, bit 3 as 4 or 5, etc., but I would really rather have multiple Y axes showing 0 to 1, stacked vertically on the same time (X) axis.
You could visualize this as multiple pens on a strip chart continuously recording different values. Each pen has its own vertical area in which it writes, but all pens could be writing data from the same numerical range.
Hmmm... I think my description might be roughly as clear as mud, but if anyone out there can figure out what I am asking and has potential solutions, please let me know.
Thanks!

Thanks. I will look at that VI, but I think I have already seen it. My problem is that I have CAN data coming in for an hour or so, but the time interval between receiving specific CAN arbitration IDs varies, so I want to plot the X axis against specific, varying time values, not a standard dT. I'm not sure I can do this on a digital graph, but I haven't given up hope yet.
BTW, I am receiving 8-byte CAN packages. Some of the bytes represent actual values, but I need to break others up into individual bit values to see error and status flag settings. Once I break the bytes into bits, I convert from analog values to digital values.

Trying to get multiple cell values within a geometry

I am provided with 3 tables:
1 - The GeoRaster
2 - The geoRasterData table
3 - A VAT table who's PK is the cell value from the above tables
Currently the user can select a point in our application and by using the getCellValue we get the cell value which is the PK on the 3rd table and this gives us the details to return to the user.
We now want to give the worst scenario within a given geometry or distance. So if I get back all the cell values within a given geometry/distance I can then call my other functions against the 3rd table to get the worst scores.
I had a conversation open for this before where JeffreyXie had some brilliant input, but it got archived while I was waiting on Oracle to resolve a bug (about 7 months)
See:
Trying to get multiple cell values within a geometry
If I am looking to get a list of cell values that interact with my geometry/distance and then loop through them, is there a better way?
BTW, if anybody wants to play with this functionality, it only seems to work in 11.2.0.4.
Below is the code I was using last, I think it is trying to get the cell values but the numbers coming back are not correct, I think I am converting the binary to integer wrong.
Any ideas?

Hey guys,
Zzhang,
That's a good spot and as it happens I spotted that and that is why I am sure I am querying that lob wrong. I always get the a logic going past the total length of the lob.
I think I am ok using 11.2.0.4, if I can get this working it is really important to us, so saying to roll up to 11.2.0.4 for this would be no problem.
The error in 11.2.0.3 was an internal error: [kghstack_underflow_internal_3].
Something that I think I need to find out more about, but am struggling to get more information on is, I am assuming that the lob that is returned is all cell values or at lest an array of 4 byte (32 bit) chunks, although, I don't know this.
Is that a correct assumption or is there more to it?
Have either of you seen any documentation on how to query this lob?
Thanks

Problem in connecting to beehiveonline via WebDAV

Hi,
I am seeing a strange behavior when connecting to beehiveonline via WebDAV. Need your help to sort out the same.
If I try to connect to https://beehiveonline.oracle.com/content/dav using internet explorer, the browser automatically redirects me to the SSO login page. After I login, it moves back to the workspace listing page successfully.
But if I try to connect to the same URL via "Add Network Location" or "Map Network Drive" the system is failing to connect. I am using the same SSO credentials. I am using Windows 7 laptop (not sure if that matters).
I have been using this (beehiveonline via WebDAV) for a some time now; this was working perfectly alright before last ~10 days. For the last ~10 days, this does not seem to work.
Can you please review and help.
Thanks, Raja

Raja,
I have some troubleshooting tips for webdav - see if any of these work and if not we can have a call and talk through the options.
Troubleshooting Tips
@ 1. While connecting to Webdav using web folders, the login prompt keeps appearing.
Try connecting to the webdav server using https url: @ http://beehive.oracle.com/content/dav
If above doesn't help, try below steps:
Stop "Webclient" service (Go to Start-> Control Panel-> Administrative Tools -> Services. Select "Web Client" and stop the service)
Set 'Startup Type' of Webclient service to 'Manual' Set up web folder using url: http://beehive.oracle.com/content/dav
(without specifying port)
2. My web folder was working properly. Now suddenly dav operations don't go thru and can not access stbeehive. I deleted the mapped network place and re-mapped, it still does not work.
This happens when the webdav server is bounced and your dav cookie on the client is not expired. Delete all cookies in Internet Explorer browser (Tools-> Internet Options - > Delete -> Delete cookies) and try reconnecting.
3. Through web folders, I created a new folder, but the folder did not appear and when I try to create it again, it says it already exists.
Stop "Webclient" service (Go to Start-> Control Panel-> Administrative Tools -> Services. Select "Web Client" and stop the service). Set up web folder using url: http://beehive.oracle.com/content/dav (without specifying port).
4. After copying a file from one folder to another within Web folder, it shows the file size as 0 bytes.
This is a known issue with the web folders client. After the copy/move operation, it does not issue a PROPFIND to get the details of the newly copied/moved file. Refresh your folder (press F5) and the correct sizes should be displayed.
5. In web folders, I double-click a jpeg file. The MS Picture Viewer application opens but it does not display the jpeg file.
The MS Picture Viewer application is not webdav enabled. Try opening the file in Internet Explorer instead.
6. I did some dav operations through the browser. After leaving idle for about an hour, it asked me for username/password again.
This is due to the dav session timeout.
7. I did some dav operations through Internet Explorer (IE). Then, I did some operations through web folders. After leaving idle for about an hour, I tried to access through IE. It did NOT ask me for username/password.
Sessions involving non-browser dav client like web folders are intended to be longer (default timeout value is 16 hours). Since you last did an operation using web folders, your dav session has been extended.
8. I have uploaded a document with a non-English name. When the document is listed, the file name is garbled.
or I have uploaded a document with non-English contents. When I open them, they are garbled.
Your dav client is not sending the encoding information correctly. Please try setting your "Content" user preferences ("document_uri_encoding", "document_character_encoding") to the encoding used by your dav client.
9. I am not logged into Web Folders. Now, I login through IE and click on a MS Office document (word/excel etc). I am prompted for my credentials again.
This can be resolved by opening the MS word document inline in Internet Explorer. Steps required to configure are available at:
http://support.microsoft.com/kb/162059.
10. I have opened a MS Office document inline in the browser. I click "Back" or close the web browser window. I am prompted to enter credentials again.
This can be resolved by following the steps given at: @ http://support.microsoft.com/kb/822128
Known Issues
Generic Issues:
@ There is no support for non-ascii username/password. Windows Vista Web folder is not supported.
Navigation through browser into URLs containing characters [ or ] may result in 404 error.
Windows Web Folders:
It throws a common error dialog box for all the error scenarios. It does not pick the message sent by the webdav server
If you create/update/delete a document and it has to go through a workflow process, Web Folders doesnt interpret the response status code correctly and throws an error.
Cadaver:
Copying/moving fails for files/folders which have spaces in their names Use cadaver ver 0.22.5 or later. Earlier versions have encoding issues.
Mac OS:
Lot of files whose name starts with the dot character like ".DS_Store" are created implicitly by Mac Finder
I uploaded a document to my personal workspace Documents folder. Then Get Info on that document in the webdav folder. There is a checkbox for "Lock". If you click the checkbox, it immediately gets de-selected. This is because this client does not send a webdav lock request.
Maybe one of these will do the trick

Variable multiple single value filled with customer exit used in FOX form.

Hi guys, I definitly need your help in the following scenario:
I have variable (multiple single value) filled in a customer exit and use it in web template. There it is used in the drop down box for selecting a special date in the analysis item. And there comes the first question:Why the results from the customer exit are written in the way "date1; date2; date3" in one line? They should appear line by line in rows. How can I influence that? I tried both data binding types, "variable" and "characteristic".
Now a button raises a planning function with a fox formula which should write the selected date (from the drop down box) in a customer table using "call function".
I always get the error, that I need to restrict the variable to "single value". Why do I have to do that and if necessary how can I do that? Other planning functions without the fox formula also work properly with using the selection from the drop down box.
I appreciate you help.
Kind regards, Anja.

Hi Vamsi.,
Try this code.
WHEN 'PREVIOUS_YEAR_1'.
IF I_STEP = 2. "after the popup of user entry
LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
WHERE VNAM = 'ZCURRENT_YEAR_PERIOD'.
break-point.
IF SY-SUBRC EQ 0.
WA_YEAR = LOC_VAR_RANGE-LOW+0(4). "Year
WA_MONTH = LOC_VAR_RANGE-LOW+5(3). "Period
WA_YEAR = WA_YEAR - 1.
CONCATENATE WA_YEAR wa_month INTO WA_FISC_PERD .
CONCATENATE WA_YEAR WA_MONTH1 INTO L_S_RANGE-HIGH .
L_S_RANGE-SIGN = 'I'.
L_S_RANGE-OPT = 'EQ'.
APPEND L_S_RANGE TO E_T_RANGE.
ENDIF.
L_S_RANGE-SIGN = 'I'.
L_S_RANGE-OPT = 'BT'.
APPEND L_S_RANGE TO E_T_RANGE.
ENDIF.
ENDIF.
ENDLOOP.
endif.
Assing points if it helps you.

Multiple On Values for Checkbox

Hi,
Is there a way to have multiple On Values for a checkbox. Also, is it possible to do this without using scripts. The forms I'm creating are used within a software application. This application dumps the data into the forms filling them as appropriate. My check boxes complete additional fields on the form for which data is not collected.
I can write scripts that will trigger these check boxes, but I cannot get them to run within the software application. I can't find an event that works. I've tried Doc Ready, but this seems to run the script prior to the data being dumped into the form.
My only answer at this point is to work around the problem and see what I can do without the use of scripts.
Any suggestions?
Karen

You can set what value the checkbox has but you cannot have multiple values. The Doc Ready is the right event to use. The checkboxes ON/OFF are set to the wrong values and hence they are not getting set.

Multiple Phase values at one frequency

Hi,
I have done the frequency response analysis for a device using the frequency response example from sound and vibration toolkit and i get multiple
phase values at one frequency how can i reduce it to one value without any error i am posting the result from the experiment please check
and give me suggestions are the stimulus and response phase values supposed to be like that????

SK,
You have serious problems in your File.VI. Why are your writing to your file and then reading it right back? Worse, there is no guarantee that the File write will actually occur before the File Read. You have a race condition set up there between those two Spreadsheet File VI's.
If you want to maintain a history of whatever has already been written to the file, you should be building it into an array and storing in a shift register. Even if your File.vi would by chance work the way you want it to, storing data in the file system is much slower than maintaining your data in memory.
As for your while loop, it is going to run as fast as it can with respect to all the functions occurring inside of it. Is it possible you are getting 14 iterations of that while loop for each frequency step that is occurring?

RandomAccessFile: How do I Clear the txt file and write multiple lines of..

Hello all,
I am a 6th grade teacher and am taking a not so "Advanced Java Programming" class. Could someone please help me with the following problem.
I am having trouble with RandomAccessFile.
What I want to do is:
1. Write multiple lines of text to a file
2. Be able to delete previous entries in the file
3. It would also be nice to be able to go to a certian line of text but not manditory.
import java.io.*;
public class Logger
RandomAccessFile raf;
public Logger()
 try
 raf=new RandomAccessFile("default.txt","rw");
 raf.seek(0);
 raf.writeBytes("");
 catch(Exception e)
 e.printStackTrace();
public Logger(String fileName)
 try
 raf=new RandomAccessFile(fileName,"rw");
 raf.seek(0);
 raf.writeBytes("");
 catch(Exception e)
 e.printStackTrace();
public void writeLine(String line)
 try
 long index=0;
 raf.seek(raf.length());
 raf.writeBytes(index+" "+line);
 catch(Exception e)
 e.printStackTrace();
public void closeFile()
 try
 raf.close();
 catch(Exception e)
 e.printStackTrace();
 }

Enjoy! The length of the code is highly attributable to the test harness/shell thingy at the end. But anyway seems to work nicely.

Connecting a KM repository from another portal to KM via WebDAV - meda data

Hello there,
we are evaluating the option of connecting a KM repository from another portal to KM via WebDAV in our Federated Portal Scenario (in fact, we wish to get rid of the the remote roles as soon as possible).
This can be accomplised as described here [Connecting a KM repository from another portal to KM via WebDAV|https://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/2783].
Or for BI as described in Note 969040 - Federated portal network and Information Broadcasting .
One question : in case meta- data properties are set, where are these stored? In the consumer portal, or in the source system, the producer portal?
I.e when I set properties on documents of the WebDav repository, and I go to the source system, will the same meta- data properties be set there?
Many thanks!

For testing I've integrated the remote KM repository as WebDAV and enabled the properties repository service :
- custom meta- data defined on the source (producer) KM system is not visible in the consumer portal if no value has been set on the source system :
Let's say you have a property 'country' on the source system, define a value for it + save, you can view the property in the consumer system.
- if you define both the same properties in consumer & producser system, you can view the properties in both system, and the value set in either one of the systems is displayed in both of them.
In short : the custom meta-data properties need to be defined on both systems

Fill BEx Variable with more than one value via Custom Exit

Dear SDN comunity,
I want to fill a BEx Variable via a custom exit. My problem is, I don't know how to fill this variable with more than one value.
I try to give you some background info based on an exaple:
Variable-Details
Type of Variable: Characteristic Value
Variable Name: ZCCD
Description: Company Code Selection
Processing by: Custom Exit
Characteristic: Company Code
Variable Represents: Multiple Single Values
This is the used ABAP code:
WHEN 'ZCCD'.
CLEAR l_s_range.
l_s_range-low = '2002;2004'.
l_s_range-sign = 'I'.
l_s_range-sign = 'EQ'.
APPEND l_s_range TO e_t_range.
The system returns this message:
Value "2002;2004" is too long for variable ZCCD
appreciate your help!

Eugene, Marcus
it works now, thx a lot!
Please find attached the final code:
CLEAR l_s_range.
l_s_range-low = '2002'.
l_s_range-sign = 'I'.
l_s_range-opt = 'EQ'.
APPEND l_s_range TO e_t_range.
CLEAR l_s_range.
l_s_range-low = '2004'.
l_s_range-sign = 'I'.
l_s_range-opt = 'EQ'.
APPEND l_s_range TO e_t_range.

TextEdit for Multiple Single values

Hi,
I have a requirement to use the select option. But select option implementations
looks very complex for me. So i am using textEdit for collecting multiple single values. Like sales order numbers need to be collected in search page to display the details in next page.
   How should i restrict the user to enter 10 degits in each line and i should i collect the each line into a range so that i can use the range variable in select statement.
Basically i am looking for splitting the continues string with newline and carraigereturns characters into a internal table.
I need to write code in onInputprocessing event.
thanks for the quick response.
Regards,
Prav

hi
use this in oninputprocessing

                               id      = 'risk'
CLEAR risk.
IF NOT textedit->text IS INITIAL.
risk = textedit->text.
ENDIF.
