The problem is that the sun-java6-javaws.desktop is incorrect. It currently runs the viewer: Exec=/usr/lib/jvm/java-6-sun-1.6.0.05/bin/javaws -viewer
It should just be javaws when you want to send it a java webstart app so it should be this: Exec=/usr/lib/jvm/java-6-sun-1.6.0.05/bin/javaws You can test this by launching a webstart app from the command line and you will see that with -viewer it doesn't work. There really is no need to launch the cache viewer this way, it can be found by running the control panel, and clicking view under Temporary Internet Files. Thanks! -- Java6 Web Start just opens the Java control panel instead of running the application https://bugs.launchpad.net/bugs/84501 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
