I really like the concept of modular bundles as implemented by OSGi. I also like "managed deployment" services like Google AppEngine (for web application) or Java WebStart (for client software). These two ideas seem to complement each-other rather well conceptually. However, the OSGi standard includes a couple of features that make i...
I have a problem modernizing a Java WebStart application under Java 6 u 13 (the latest at this moment) We desire to use the new mechanism to have several master configuration files each with their own configuration , which then "include" another jnlp file which is autogenerated to ensure that the jar list is accurate. After quite a...

I need to prevent users from starting my Java application (WebStart Swing app) multiple times. So if the application is already running it shouldn't be possible to start it again or show a warning / be closed again. Is there some convenient way to achieve this? I thought about blocking a port or write sth to a file. But hopefully you ca...
I'd like to write an applet (or a java Web start application) calling its server (servlet?) to invoke some methods and to send/retrieve data. What would be the best way/technology to send and to retrieve those message ? ...
I get an UnsupportedClassVersionError thrown when launching jnlp, however when I try to run the relevant jar files from command line everything works fine. I tried setting j2se versions to 1.5+, 1.6+, using signed/unsigned jar files, but all that doesn't help. I'm trying to launch my own jar file with two supporting jar files (mysql-con...
Every time we update our Java application (Java client and Java server) we have the problems that some clients approx. 1% - 2% does not load the new jar files. This occur with applets and also with Java Web Start. If you clear the Java Cache then all is working correct. Any idea why Java does not check for new jar files on every start? ...
I designed a GUI program using Netbeans 6.5 on a computer running Vista. I uploaded it to my server and tested out the web start. It worked fine. Later when using a Mac, it was not able to work. I tested it out in Ubuntu and was unsuccessful as well. I even tried to compile the source code on Ubuntu and I got this: Task required to...

Hello. I have been able to create a JNLP file, which successfully sets up a splash screen & a desktop icon for a Java program launched through Web Start. Here's the relevant chunk of the JNLP: Now, to launch the program, I find I can either click on the JNLP, in which case the splash screen shows, or on the desktop icon, in w...
I use the shortcut tag in my appliation's jnlp descriptor to create a desktop link and a menu entry for my application. If these shortcuts get deleted on the client - how can they be reinstalled automatically without user action? Is there a configuration option for the jnlp file? (btw I'm using java6) ...
If my jnlp descriptor on the server changes and I start my application from the browser, a new jnlp file will be created in the cache and my desktop shortcuts will be updated to use the new jnlp file. (that's good so far). But if I start my app using the desktop shortcut (or the menu entry), then my app won't know about the changed jnlp...
Hi. Summary for those who might not want to read that much: How do I do this: ? If we could pass ad-hoc command-line args to javaws, then javaws apps could be more like "1st class citizen" "ordinary application". E.g. we could pass filenames of files to be opened. I would like to know if there is a way to pass "ad-hoc" command line arg...

I have packaged up all of the Windows dlls from inside c:\tibco\tibrv\bin into a Jar file and have added these to the nativelib element in the JNLP file. I was hoping that webstart would take the dll files ...
