How can I use a relative path in a Virtual Directory tag?

That is probably a bit vague, so I will explain in more detail. We are using BEA
WL Portal 7.0 and our team is developing multiple portal applications. We have
a core set of portlets (consist of JSPs) that we need to reuse in multiple portals
(Web Apps), however from a version control perspective they need to reside in
one common location. So, the solution I came up with is to use a virtual directory
for the the common directory and add this to weblogic.xml for each web app. This
works fine. However, each developer has different directory names for their project...ClearCase
view names to be specific... plus we have integration views, QA views, etc...
so we can't have any "C:\mystuff\mydomain" absolute paths anywhere in the portal
configuration. Does anyone know of a way to use a relative path for a virtual
directory? I have tried various versions of ../../ for example to try to backup
and then recurse down to the directory, but this is not working. Any ideas?
By the way this is basially just a hack for development, when we package the WAR
for QA, Prod, etc... we copy needed files and there are no virtual directories.
In other words, I don't care how "creative" solution is :)
This is what I have right now, which I need to replace with a relative directory
name:
<virtual-directory-mapping>
<local-path>C:/Projects/TouchPoint_v1.0_Fix/tp_portal/bipiportals/beaApps/portalApp/tp-shared</local-path>
<url-pattern>*</url-pattern>
</virtual-directory-mapping>

Well, in fact you can in a special case :
- The file you want to access is in the same directory than the applet (or in a sub-directory)
If this condition is OK, you can open the file using :
java.io.InputStream MyInputStream = <YourAppletClassName>.class.getResourceAsStream("sidira_interactif2.svg")
With this stream, its easy to read the file content.

How can I open a relative path

Does somebody knows how can I open a relative URL from an applet by the
getAppletContext().showDocument(new URL("http://java.sun.com"), "_blank");
instruction?
I mean, I want to open a html page stored in my hard drive but if I change the "http://java.sun.com" to, for example, "Mi documents/index.html" it doesn't works.
Could sombody help me with this please?

How can i specify username/password while creating a virtual directory

Hi,
i m trying to create a virtual directory in 9iAS on a mapped drive. How can i specify which username password to use to enable to connect to the network mapped drive. Is there any way where we can specify username / password ???
thanks
Unmesh

9iAS R1
Run the report service as a local account with administrator rights.
On the target server, create a local account with the same user name and password.
Now you can use the hidden shares ($) for example:
&destype=file&desname=\\servername\d$\report_output\report.pdf
9iAS R2 and 10g
Pretty much the same thing except by default, the report server runs inline. I have not been able to get the entire service to run as a particular user. To get around this, I created a report server service and do not run the reports in process. It uses the separate service.
rwserver -install rep90_name
edit <ORACLE_HOME>\reports\conf\rwservlet.properties file.
SERVER_IN_PROCESS=NO
SERVER=rep90_name
Edit service for rep90_name and change it to run as local administrator user you created on both servers and then start the service.

Can any one suggest me how can I use relative path inside SSIS pacakge to access config file ?

Can any one suggest me how can I use relative path inside SSIS pacakge to access config file ? Please help me as its urgent.THanks for your help in advance.

Hi Jay,
SSIS can only recognize the absolute path of a XML Configuration file, the relative path is not supported. Furthermore, if the XML Configuration file is already generated, we can use the Environment variable package configuration type instead so that
SSIS runtime automatically looks for the configuration file from the path defined in the environment variable. This is convenient when we need to deploy a package to different environment. We only need to define the environment variable for package configurations
once on each server, and then the variable can be used by all the packages on this server.

Relative path for Download directory folder.I created a firefox profile and i wanted to use this profile in multiple machines.I wanted to use a relative path for download directory with respect to the profile folder.I need this on Linux machines

I have a use case where I need to use different download directories with different firefox profiles.I need to use this profiles in multiple linux machines.
I need to have a relative path to my download directory with respect to the profile folder.
Ex: I have a selenium test which opens a website and downloads it to my machine.I want this downloaded file to go into some specific folder relative to this profile folder.How do I do this??

That is not a practically empty xinitrc - that file only needs one line: exec WM. Other things are entirely optional, and some of them very useful, but I'd encourage you to stick with the simplest xinitrc that will do what you require.
Is slim involved? Probably. That is the source of many problems. But to start narrowing this down, I have 3 suggestions:
1) temporarily (at least) change your inittab to default to runlevel 3 ... actually, is it currently set to 5 or 3? if it is currently 3 that would explain why slim doesn't start.
2) at a tty in runlevel 3 use "xinit" instead of "startx". Startx is fine most of the time, but it is essentially just a complex wrapper for xinit. That complexity can often iadd useful functionality, but it *always* makes troubleshooting more difficult. So for now just use a vanilla 'xinit'.
3) remove dbus-launch from your exec line in xinitrc. This is done by console-kit so it is redundant and potentially problematic. Further BOTH of these are taken care of by slim, so I'd even suggest getting both a jump start on being ready for slim and simplifying troubleshooting by removing both of them. Just make that line "exec openbox-session"
Edit: adding one more:
4) temporarily switch out openbox-session for openbox. I suspect the reason feh's setting of the background is getting overridden is due to a script or setting in openbox's autostart settings - many of these are only invoked when "openbox-session" is called, while "openbox" starts *just* the window manager itself.

How can i use my iphone with more than one itunes

how can i use my iphone with more than one itunes

Sync iPod/iPad/iPhone with two computers
Although it isn't possible to sync an Apple device with two different libraries it is possible to sync with the same logical library from multiple computers. Each library has an internal ID and when iTunes connects to your iPod/iPad/iPhone it compares the local ID with the one the device normally syncs with. If they are the same you can go ahead and sync...
I have my library cloned to a small 1Tb USB drive which I can take between home & work. At either location I use SyncToy 2.1 to update the local copy with the external drive. Mac users should be able to find similar tools. I can open either of the local libraries or the one on the external drive and update the media content of my iPhone. The slight exception is Photos which normally connects to a specific folder on a specific machine, although that can easily be remapped to the current library if you create a "Photos" folder inside the iTunes Media folder so that syncing the iTunes folders keeps this up to date as well. I periodically sweep my library for new files & orphans with iTunes Folder Watch just in case I make changes at one location but then overwrite the library with a newer copy from the other. Again Mac users should be able to find similar tools.
As long as your media is organised within an iTunes Music or Tunes Media folder, in turn held inside the main iTunes folder that has your library files (whether or not you let iTunes keep the media folder organised) each library can access items at the same relative path from the library folder so the library can be at different drives/paths on different machines. This solution ensures I always have adequate backups of my library and I can update my devices whenever I can connect to the same build of iTunes.
When working with an iPhone earlier builds of iTunes would remove any file not physically present in the local library, even if there was an entry for it, making manual management practically redundant on the iPhone. This behaviour has been changed but it will still only permit manual management with a library that has the correct internal ID. If you don't want to sync your library between machines on a regular basis just copy the iTunes Library.itl file from the current "home" machine to any other you want to use, then clean out the library entries and import the local content you have on that box.

How can I use a 3rd party XML parser such as xerces with OC4J ?

Hi all tech experts,
I am using Oracle Application Server 10g Release 2 (10.1.2) and i have
installed Portal and Wireless and OracleAS Infrastructure on the same
computer.
i tried all the solutions on this thread
Use of Xerces Parser in out application with Oracle App Server 9.0.4
but still fighting.
I have also posted this query on OTN on following thread
How can I use a 3rd party XML parser such as xerces with OC4J?
but no reply....
Please help me on this issue.
Since OC4J is preconfigured to use the Oracle XML parser which is xmlparserv2.jar.
i have read the following article which states that
OC4J is preconfigured to use the Oracle XML parser. The Oracle XML parser is fully JAXP 1.1 compatible and will serve the needs of applications which require JAXP functionality. This approach does not require the download, installation, and configuration of additional XML parsers.
The Oracle XML parser (xmlparserv2.jar) is configured to load as a system level library of OC4J through it's inclusion as an entry in the Class-Path entry of the oc4j.jar Manifest.mf file. This results in the Oracle XML parser being used for all common deployment and packaging situations. You are not permitted to modify the Manifest.mf file of oc4j.jar.
It must be noted that configuring OC4J to run with any additional XML parser or JDBC library is not a supported configuration. We do know customers who have managed to successfully replace the system level XML parser and the Oracle JDBC drivers that ship with the product, but we do not support this type of configuration due to the possibility of unexpected system behavior and system errors that might occur from replacing the tested and certified libraries.
If you absolutely must use an additional XML parser such as xerces, then you have to start OC4J such that the xerces.jar file is loaded at a level above the OC4J system classpath. This can be accomplished using the -Xbootclasspath flag of the JRE.
i have also run the following command
java -Xbootclasspath/a:d:\xerces\xerces.jar -jar oc4j.jar
but no success.
How could i utilize my jar's like xerces.jar and xalan.jar for parsing instead of OC4J in-built parser ?
All reply will be highly appreciated.
Thnx in advance to all.

Hi Neeraj Sidhaye,
I am trying to deploy a sample xform application to the Oracle Application Server (10.1.3). However, I encountered the class loader issue that is similar to your stuation. I tried all the three solutions but the application is still use the Oracle xml paser class. I am wondering if you have any insight about this?

How can I use the built-in Isight camera with an external camera (usb/firewire) at the same time?

How can I use the built-in Isight camera and an external video camera at the same time?
I'm wanting to stream over Oovoo/Skype/etc. using 2 cameras.
Thanks

Simple question with a not so simple answer.
(a) If you mean that you want to run multiple apps simultaneously using a different camera with each app, you may encounter computing power limitations. Digital video is processor intensive. The only way to know if your Mac can do this it to try it. If the video does not work together but each app works when it it the only app running, you are likely overloading your Mac's ability to process and/or move all the required data in your data bus. You can get a better indication of whether this is the case by watching your Activity Monitor utility while running the apps you want to use.
(b) If you mean that you want to have more than one compatible camera connected to your Mac simultaneously for ease of changing between video sources, some, but not necessarily all, apps you are using to operate your camera(s) allow you to select between your cameras.
How you select among connected cameras depends on which application you are using. Here is how camera selection works in a few examples:
(1) For iChat, you can choose which iSight you use in the "Camera:" choices bar in iChat > Preferences... > Audio/Video that appears when more than one compatible camera is connected. Although your camera choices will be different, the choices bar will look something similar to the Preferences settings shown here:
If you cannot see the "Camera" choices bar, your Mac is recognizing only one (or none) of your cameras. In that case, consider the suggestions fromhttp://support.apple.com/kb/HT2090 for iSight problems or refer to your other camera's documentation for help.
This particular choices bar solution applies ONLY to iChat. Most other applications also have settings that allow you to choose which camera to use. However, they do not all work the same way.
(2) For instance, iMovie HD's camera choice is NOT set via Preferences. When you have more than one compatible camera connected, iMovie6 HD uses a drop-down menu choice something like this (depending on which version of iMovie you use):
Note: Because I had no built-in iSight connected when I made this example, and because my external iSight was not connected, the drop-down menu showed only "Time Lapse." Because your Mac has a built-in iSight, your built-in iSight would show in the drop-down menu even when no other camera is connected. Connecting an additional Mac compatible webcam should allow you to choose either camera.
Other iMovie versions work slightly differently.
iMovie 9 (from iLife '11) uses a different camera choice button shown in this article:
http://docs.info.apple.com/article.html?path=iMovie/9.0/en/mov39f84285.html
iMovie 8 (from iLife '09) is slightly different as explained in this article:
http://docs.info.apple.com/article.html?path=iMovie/8.0/en/10172.html
In general, you can use your Mac's help for the application in use to find out how to select among more than one connected camera.
(3) Photo Booth in Snow Leopard 10.6.x and later uses the Photo Booth > Camera menu command to select which camera to use.
Note for readers with older Mac OS X: The previous version of Photo Booth that came with Tiger (10.4.x) is such a simple, basic app that it offers no menu selectable choice. Unless your built-in iSight is already occupied as the camera being used by some open application before you launch Photo Booth, Photo Booth will use ONLY your built-in iSight.
However, you can use the trick from ¶ 4 of http://docs.info.apple.com/article.html?artnum=302781 to let Photo Booth use an external camera.
(If you have an external Firewire camera connected, it may be used in preference to any USB webcam. If that is a problem for you, merely disconnect the problem Firewire device.)
(4) For FaceTime, launch the app and click the Video menu item.
If your Mac recognizes more than one connected compatible camera, a "Camera" section listing the cameras from which you can choose will appear there. Clicking on the desired camera name will let you select the one you want as shown in this image from my Mac Pro and LED Cinema Display:
If your Mac recognizes only one compatible camera, the "Camera" section will not appear in the Video menu, but FaceTime will automatically use the connected camera that is recognized by OS X.
(5) I do not use Skype oir Oovoo. For those or other apps, see Help for each app for info on how to select your desired camera.

How can i use dsadm to change the ldap port?

I have a ldap with port 1389,I changed it to 389,now I can not start it because it is a non root user.
Now I want to change the port back to 1389,but I can not use dsconf because the server is not running.
How can i do now? How can i use dsadm to change the port?
Thank u very much.

My apologies, I didn't mean to be rude/impolite.
I just wanted to emphasize that in a situation where a Directory Server doesn't even start, you cannot interact with the live server to configure the new port (either talking LDAP or otherwise). All you can do in that case won't be related with the LDAP (that's just the name of the protocol): either assigning network privileges to the user, or changing the Directory Server configuration file.
The other thing I'd like to outline (and this could take a separate thread ;-) ), is that semantically, I'd prefer talking of a Directory Server instead of an LDAP Server because the former is 'something' providing Directory Services, whereas the latter is just the name of the protocol we use to interact with the server; but this is just my personal opinion, you don't have to agree with me.
that's all folks!

How can I use "write to spreadsheet" during the data is taking but not the end of all the loops

Hi,
I have to run an experiment on Labview 6 or 5. I don't have Labview 7 on that computer for some reason. My experiment is talking about 1000 hours, and I have a probelm on storing the data. Right now I am using "Write to spread sheet" and I set the "append" to false. And the data is installed at the end of the experiment, that means after 1000 hours. In the mean time if somthing oges wrong like power cut or what, I will lose all the data. So what I want to do is to save the data evertime when the data is took. I tired to set the "append" to true, but it does not let me to choose the "file path"--- when I choose this and select write on new or excisting file, it said" you may not be able to save on a exciting file" and it does not let me create a new file either. If anyone have the lidea like how can I use the "wrtie to spreadsheet" function and at the same time can install the data everytime inside the look, please let me know. Thanks alot.
KL

KL,
It sounds like you want to periodically save your data so it is in smaller files. (great idea) For this operation you will not want to append the data...if something happens to your system while the file is open it could become corrupt and ruin all the data. You need to write the new block of data to a new file every time. Now...this depends on how big your data is...if you only have like 500k of data to write in a block you should probably write several blocks before starting a new file. I don't know enough about how much data you are acquiring. In either case...the write to spreadsheet file.vi will need a different name each time it is called and you will not want to append. Append = false.

How can we use Custom MessageBox in SelectionChangedEvent of LongListSelector for Windows Phone 8

Dear Sir/Madam,
How can we use Custom MessageBox in SelectionChangedEvent of LongListSelector for Windows Phone 8.
Actually my problem is that When i am using Custom MessageBox in SelectionChangedEvent of LongListSelector,when i am click Open(Left Button) it's working fine and navigated correctly,But when i am Click the No(Right Button) then it stayed in same page
but all that page is in stuckup i mean that page is not working and not doing any event.
My C#.net Code
private async void userPageLongListSelector_SelectionChanged(object sender, SelectionChangedEventArgs e)
if (e.AddedItems.Count > 0)
if (userPageLongListSelector.SelectedItem == null)
return;
if (dbTenMin == null)
dbTenMin = new Database(ApplicationData.Current.LocalFolder, "tenMInDBSchema.db");
await dbTenMin.OpenAsync();
var res = (sender as LongListSelector).SelectedItem as _10Min._10MinClass.minUserPages;
var resIndex = (sender as LongListSelector).ItemsSource.IndexOf(userPageLongListSelector.SelectedItem);
string selectedPageName = res.userPages.ToString();
string selectedPageDesignUser = res.pageDesignUser.ToString();
int selectedIndex = resIndex;
CustomMessageBox messageBox = new CustomMessageBox()
Caption = "Message...!",
Message = "This form need offline datalist,Please load now.",
LeftButtonContent = "Open",
RightButtonContent = "No"

break;
case CustomMessageBoxResult.RightButton:
break;
case CustomMessageBoxResult.None:
break;
default:
break;
messageBox.Show();
Same custom messagebox code working in Phone_BackKeyPress event i am writing the code in Right Button that e.OriginalSource.ToString(); then it is working fine.
But It is not working in Selection Changed Event in LongListSelector control in Windows Phone 8.
Please help me,as soon as possible.
Thanks & Regards,
SrinivaaS.

What happens if you leave the implementation for LeftButton empty as well , does the page gets stuck in that case also, if you press left button?
i.e.
CustomMessageBox messageBox = new CustomMessageBox()
Caption = "Message...!",
Message = "This form need offline datalist,Please load now.",
LeftButtonContent = "Open",
RightButtonContent = "No"
messageBox.Dismissed += (s1, e1) =>
switch (e1.Result)
case CustomMessageBoxResult.LeftButton:
break;
case CustomMessageBoxResult.RightButton:
break;
case CustomMessageBoxResult.None:
break;
default:
break;
messageBox.Show();

How can I use a progress bar in objective c mac

How can I use a progress bar in objective c mac? I have a code that downloads a file and I want to be able to let the progress bar increase by 1. A bit further on the code (to download the file) it needs to increase again. And so on...
My code
-(IBAction) downloadButtonPressed:(id)sender;{
    //get the path to the image that we're going to download
    NSURL *url = [NSURL URLWithString:@"https://www.dropbox.com/s/l6o07m48npxknt4/Cluedo.zip?dl=1"];
    //get the path to documents folder where we're going to save our image
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *DocumentsDirectory = [paths objectAtIndex:0];
    NSString *filePath = [DocumentsDirectory stringByAppendingPathComponent:@"Cluedo.zip"];
    //Download the file to memory
    NSData *data = [NSData dataWithContentsOfURL:url];
    NSError *error = nil;
    //Save it on the Documents directory
    [data writeToFile:filePath options:NSDataWritingAtomic error:&error];
    NSFileManager* fm = [NSFileManager defaultManager];
    NSString* zipPath = filePath;
    NSString* targetFolder = @"/Applications"; //this it the parent folder
    //where your zip's content
    //goes to (must exist)
    //create a new empty folder (unzipping will fail if any
    //of the payload files already exist at the target location)
    [fm createDirectoryAtPath:targetFolder withIntermediateDirectories:NO
                   attributes:nil error:NULL];
    //now create a unzip-task
    NSArray *arguments = [NSArray arrayWithObject:zipPath];
    NSTask *unzipTask = [[NSTask alloc] init];
    [unzipTask setLaunchPath:@"/usr/bin/unzip"];
    [unzipTask setCurrentDirectoryPath:targetFolder];
    [unzipTask setArguments:arguments];
    [unzipTask launch];

Your code really isn't suitable for a progress bar, not a real one anyway. Your code will spend about 99.9% of its time in the method "dataWithContentsOfURL:url". That is not a method you want to use in the real world. It is only for demos or proof of concept exercises. All network operations should be asynchronous. That gives you the ability to gracefully recover when there is a failure and also to do fancy things like display a progress bar and tell the user when the download is complete.
Once you get the asynchronous download logic working, then you can worry about the progress bar. The first thing you will need is the size of the file. Without that, all you can ever do is an indeterminate progress bar or spinner. If you have the size of the file, then you can keep track of how much of the file you have downloaded and update your progress bar with the percentage complete. Make sure to throttle it to no more than incrementing by 1% at a time. Otherwise, a large file or a file transferred in many small chunks, would waste too much time updating the progress bar for no change.
