Description of problem: I tried to install the Java Web Start application available at http://www.familysearchindexing.org/. The browser popped up a window that showed messages about downloading a bunch of jars. Then the window disappeared and nothing more happened. I found this in ~/.xsession-errors: *** NSPlugin Wrapper *** WARNING: unhandled variable 11 in NPP_GetValue() *** NSPlugin Wrapper *** WARNING: unhandled variable 11 in NPP_GetValue() *** NSPlugin Wrapper *** WARNING: unhandled variable 11 in NPP_GetValue() *** NSPlugin Wrapper *** WARNING: unhandled variable 11 in NPP_GetValue() *** NSPlugin Wrapper *** WARNING: unhandled variable 11 in NPP_GetValue() *** NSPlugin Wrapper *** WARNING: unhandled variable 11 in NPP_GetValue() Window manager warning: Invalid WM_TRANSIENT_FOR window 0x3c00007 specified for 0x3c00011 (Choose a c). netx: Launch Error: Could not launch JNLP file.

Visit http://www.familysearchindexing.org/ 2. Click on the software installation link in the lower left-hand corner Actual results: Jars are downloaded, but the application fails to start. Expected results: The application should start. Additional info: This appears to be similar to, but distinct from, bug #475081.
This issue is happening due to combination of a bug in the site, and a missing feature in NetX. JNLP specifications allow for requesting a basic jar from the site afaict: http://java.sun.com/j2se/1.5.0/docs/guide/javaws/developersguide/downloadservletguide.html#mapping The download server that www.familysearchindexing.org redirects to, does not support basic download request. Since it is the only protocol NetX supports, the app fails to load.

this should be in rawhide within the next couple of days: http://koji.fedoraproject.org/koji/taskinfo?taskID=1098935
Should we expect the changes to be back ported once proven to work in rawhide or will F11 be the first stable release to see the fix?
will be in f-10 soon. the update has been requested
(In reply to comment #5) > will be in f-10 soon. the update has been requested Excellent, thanks for the update.
java-1.6.0-openjdk-1.6.0.0-9.b14.fc10 has been pushed to the Fedora 10 stable repository. If problems still persist, please make note of it in this bug report.
I ran a JNLP in Fedora 10 with java-1.6.0-openjdk-1.6.0.0-15.b14.fc10, Firefox 3.0.10 and got the similar problem: net.sourceforge.jnlp.LaunchException: Fatal: Launch Error: Could not launch JNLP file. at net.sourceforge.jnlp.Launcher.launchApplication(Launcher.java:372) at net.sourceforge.jnlp.Launcher$TgThread.run(Launcher.java:600) Caused by: java.lang.NullPointerException at net.sourceforge.jnlp.Launcher.launchApplication(Launcher.java:358) ... 1 more Caused by: java.lang.NullPointerException at net.sourceforge.jnlp.Launcher.launchApplication(Launcher.java:358) at net.sourceforge.jnlp.Launcher$TgThread.run(Launcher.java:600) The JNLP can run on Windows XP with Sun JDK 1.5.0_06. Is this the same bug or my mistake?

Could you please post a link to the JNLP file?
We're writing a java client to launch on a static html page in a CD-ROM. Now we found how to resolve the problem: In Windows JNLP: <jnlp spec="1.0+" codebase="file:." href="search.jnlp"> In Linux JNLP: <jnlp spec="1.0+" codebase="." href="linux_search.jnlp"> Sorry for disturbing you.
