Connecting Directly to Day CRX using RMI

Has another successfully connected to DAY CRX using the com.day.content.spi.jsr170.RMIRepository connection class?
the document: http://e-docs.bea.com/wlp/docs92/day/pdf/day170adapter_developers_guide.pdf makes it seem very quicky and easy yet after multiple times keep getting:
####<Sep 27, 2007 4:46:02 PM EDT> <Error> <ContentManagement> <gnwricl2013818> <AdminServer> <[ACTIVE] ExecuteThread: '6' for queue: 'weblogic.kernel.Default (self-tuning)'> <weblogic> <> <> <1190925962680> <BEA-000000> <
com.bea.content.RepositoryException: Unable to lookup: crx
I have a support ticket open but I have actually heard of anyone successfully connecting to Day CRX from BEA.

You will need a Thunderbolt to Ethernet adapter.

How to connect VCR with DAY CRX

Hi all,
we try to connect Day CRX as content repository in WLP 10.2. We followed the documentation in http://edocs.bea.com/wlp/docs102/pdf/day170adapter_developers_guide.pdf. This sounds very easy - but does not work. Entering the Connection Class "com.day.content.spi.jsr170.RMIRepository" while adding a new repository connection, we get an "Type of connection class is invalid" error.
Any ideas what's going wrong here?
Thanks in advance.

My guess is that this is the issue tracked with CR367383: "Validation in BrowseReposBaseController too strict - cannot connect old-style SPI implementation". There is an easy workaround but you can request a patch if you want to. Reference the CR if you open a support case for a patch.
This has been fixed in the next release. It is supposed to be in the release notes for 10.2, but I don't see it there. This is what it was supposed to say:
Title: CM: Unable to add repository config for some non-BEA repositories via WLP Admin Tools due to 'Class.isAssignable error'
Description:
The WLP Admin Tools currently do not allow one to create a repository configuration for certain non-BEA repositories which implement the old SPI
interface. However, this is not a CM limitation. If the repository configuration is manually created in the content-config.xml file, it will work as expected.
Platform: All
Workaround: If you are unable to create a repository configuration via the WLP Admin Tools, manually edit the application's META-INF/content-config.xml file and add a section like the following:
<content-store>
<name>myRepository</name>
<class-name>com.my.repository.class</class-name>
<repository-property>
<name>cm_fireRepositoryEvents</name>
<value>false</value>
</repository-property>
<read-only>false</read-only>
<search-is-enabled>true</search-is-enabled>
<fulltext-search-is-enabled>false</fulltext-search-is-enabled>
<search-indexing-is-enabled>false</search-indexing-is-enabled>
</content-store>
Then redeploy the application, and it should be visible via the WLP Admin tools.
Note that if you have a deployment plan, the domain configuration may override the content-config.xml configuration.

Sending Connection Object over the Network using RMI

Hi,
How can a Connection object be sent over the network and run on another JVM. I need to hold connection object to execute processes one after other, that require Oracle connection without ever connecting again. I do not have J2EE container or webserver setup to hold connection/connectionpool,but need to run the process on command line. I am using RMI infrastructure to pass parameters/return values but connection object is not serializable and connot be marshalled and failing. Please explain, if there is another way using JDK 1.4
Sudheer

I think that what you want to do is connect to the database on the RMI server object, then use the server object from your remote clients to execute the processes you require to rrun.

Can't connect MBP to LCD projector using DVI-TO-VGA adapter

I am trying to connect my MacBookPro to a Hitachi CP-X885 projector, which I normally connect an IBM Thinkpad to at 800x600 or 1024x768. I also use my MBP and the VGA adapter to connect to other LCD projectors and monitors (so my adapter works, as well as both systems, projector, cables, etc.). Problem is, that when I connect my MBP to the projector (I have to connect it via VGA as there is a 250 foot cable that goes to the front where the rear-projection takes place). When I do the "detect displays" nothing is detected. I also connected directly to the projector using a shorter cable, same thing (doesn't detect it). So, is the projector not supplying some type of signal to the output, that the MBP wants to see?)... is there a way to FORCE the MPB to have output? I know that if there is signal, it will display (we have LOTS of notebooks that display to the projector just fine, BUT have SEVERAL MBP's, and NONE of them will detect, and we've tried several adapters (just to be sure)... HELP!... is there some way to FORCE output from the MBP instead of it having to DETECT IT???
Thanks!

Sorry Walter, but according to the Terms of Use (which you agreed to the first time you logged in to the Discussions and can be found if you click on the "Help" link to the right):
Do not post a URL unless it directly answers a user's question.
The URL you post does not answer David's original question. Also, it could potentially void his warranty because a firmware hack (and this is indeed a link to a "hack") is an unauthorized alteration to the hardware of his computer. ("Software" can only be installed on the hard drive and that hack is not installed on the hard drive, it's installed on the firmware on a chip inside the logic board.)
I don't want to take this thread off-topic, but your reply does NOT help David's situation. I would, however, value your input and anyone else's to this and any other topic in the Discussions as long as it is pertinent to the original subject.

Connection to CRX via RMI and getting WeakReference value..... with an exception!

Hi there,
I have the following problem.
I opened a ticket in Day Care Support system, about CRX users/group membership that got lost while synchronization with our LDAP server.
Although when the user and the group had been created (and therefore taken from that same LDAP server), the membership was good.... but after some time the membership got lost......
So what i am trying to do now is a Java program that connects to CRX via RMI.
And gets the list of all the users from a group (aka membership).
The idea is to monitor the membership each seconds.
But when trying to get the property "rep:members" of the group, I have the following exception :
javax.jcr.ValueFormatException: Unknown value type 10
          at org.apache.jackrabbit.rmi.server.ServerObject.getRepositoryException(ServerObject.java:13 9)

          at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:322)"
I searched a little bit and found that "10" is the number for type WeakReference.
That's normal to me because memberships are stored in the group as a list reference to users linked to that group....
Anyways, what's not normal to me is that when the type is "10" the API does not let me get the Value (cf. ServerProperty.getValues() method)

Using Time Capsule with Windows 7. Won't work when modem connected directly to Time Capsule, must be connected through another router.

Apple Time Capsule working with Windows 7 PC will not work when modem is connected directly to the Time Capsule. Only when a Cisco Linksystem is connnected inbetween the modem and the Time Capsule.

Sorry but it needs much more specific info than this..
What modem? Is it cable or adsl or some other?? Is it pure modem or broadband router included?
Cable has specific issues different to adsl.
If you used to use the Cisco/linksys router.. and have not reset the cable modem it will not work. Turn off the cable modem.. it must be powered down.. if battery backup drop out the battery. Remove the coax cable.. get it off. Power down everything else in the network.
Plug in the modem to the TC wan port.
Power up the modem.. wait 2min
Power up the TC.. wait 2min
Power up the clients.
If it has worked you will now be able to open the airport utility on the windows computer and see the TC has a public ip on the WAN port. If not redo the whole thing but leave the modem off.. 15min.. 1 hour.. 1 day.. ring the cable company and ask them to reset. Usually a few minutes is enough.
If you have a modem with combined router.. then bridge the TC. Just google search it.
For other combos.. tell us specifics..

I used to send photos from my Lumix Tz-40 camera directly to my iPad using the cameras WIFI. Since I installed IOS7 the connection no longer works. Anyone got any ideas. I have already installed the latest version of Panasonic's Image App (1.7.1)

I used to send photos from my Lumix Tz-40 camera directly to my iPad using the camera's WIFI. It was all working well until I installed IOS7. The connection no longer works. The camera still keeps the iPad in its connection history. The camera's wifi network still appears when I select a WiFi network from the iPad but the Wifi status icon never appears on the iPad. So the connection is never made.
Anyone got any ideas. I have already installed the latest version of Panasonic's Image App (1.7.1)

Hi there,
You're running an old version of Safari. Before troubleshooting, try updating it to the latest version: 6.0. You can do this by clicking the Apple logo in the top left, then clicking Software update.
You can also update to the latest version of OS X, 10.8 Mountain Lion, from the Mac App Store for $19.99, which will automatically install Safari 6 as well, but this isn't essential, only reccomended.

I have CS 6 which requests I sign in to access my serial numbers, which I have already, and it fails to connect so that I cannot use the programs. How do I get past this, is there a direct line to customer support?

Using Connect:Direct with SAP

Folks,
Client is using Connect:Direct to transfer the files from one location to another location.There are two table maintained namely T9AOA and T9AOB with Interface id and Unix scripting w.r.t Processing types respectively.
1.I don't think these are SAP standard tables then why they are not named starting with Z or Y
2.How to use Connect:Direct with SAP.
Searched in SDN and google but didn't get any clear information on the above.From google I came to know this is a Product of Sterling Commerce(AT&T).
Hope someone here who used Connect:Direct with SAP can share the info.
Thanks,
Kiran.

Paky,
The existing Design,had some tables which were maintained with required Unix Scripts.In the program we are just fetching that script from the table and building a Unix Command to move the files.There is also a URL using which we can check the status of the files.As I was just using the already existing design,don't have much info on how C:D connectivity can be designed from scratch.
By Googling,I was able to get some info.May be it will give you some lead.

How To Ask Questions The Smart Way
Eric Steven Raymond
Rick Moen
Write in clear, grammatical, correctly-spelled language
We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.

Drawing connected direct lines using the mouse

Hallo all,
What I want to do is, to draw connected lines on a graph using just the mouse...
First I will define min and max values for (x,y) -graph range- using the property node...
Then using the mouse I want to draw frequency ramps over time like in FMCW modulation... For example it will just draw the ramps by connecting several points marked by my mouse clicks on the graph. Moreover I need the (x,y) values that I click on the graph...
Thanks,
Ogulcan

Hmm, this does not sound very clear. Do you want the cursor to follow the mouse even when the mouse button is up. If you have multiple cursors, which one should be followed? What should happen if you move the mouse outside the window? How do you release the cursor from the mouse when done?
I think it is much easier if you just drag the cursors via the normal mechanism. It is most direct and intuitive. See attached LabVIEW 7.1 example. For another example of moving points, have a look at this older thread..Message Edited by altenbach on 06-28-2005 10:13 AM

Upgraded one iPad to 8.1 about 10 days ago since then have to restart wireless hub each day to use, other iPad on previous os no problem until upgraded yesterday now have the same problem although both devices show wireless connection.

we have two iPads (ipad2 and an iPad mini). The ipad 2 was upgraded to os 8.1 about 10 days ago, since then I have to restart my wireless hub every day to use the ipad. I have however been able to use the iPad mini running on the previous os without any problem. Last night I upgraded the mini to os 8.1 and this now suffers the same problem. Both iPads display a strong wireless signal to my hub but don't want to seem to connect. I have had BT check my broadband connection and they found no problem, whatever is causing it has happened since upgrading from 8.0.2 to 8.1

Do you have an updated version for your AirPort?

Webdav EXTREMELY slow, now trying to connect directly to a WFE bypassing F5 using UNC

We are having problems with Explorer mode being VERY slow in multiple SP farms, (2010 & 2013), and are trying to get to the root of the problem.
We are trying to map a UNC path out directly to a server using something like \\servername\sitecollection\site\library and we can't get it to work. Can anyone tell me how to do that? I know I've done this way back in the past (2007) and assume
that it should still work in 2010 and 2013.
Failing that, can anyone offer any suggestions on things to look for with Explorer Mode being extremely slow? We are getting like 1.15kbs download speeds in EM, where if we just download a document from the site via a Standard View it works just fine.
We've been googling like crazy and having come up with anything so we thought we'd try to take the F5 out of the picture.
We've had several conversations with the networking team, which they claim that they are not throttling webdav in any way, and we can't figure out anything else that would allow webdav to get through, but just be VERY slow.
Thanks.
Ted

Up front, WebDAV connections are slow. To diagnose issues with WebDAV, you would need to introduce packet sniffing on the client and server (using Network Monitor 3.4 is an option).
The Web Application must respond to the name you're trying to map. For example, if the Web Application had an Alternate Access Mapping and IIS Site Binding of "servername", then you could use it. If not, you can't. Generally you do not use server names in
AAMs or IIS Site Bindings.
