Comment 1 Peter Gückel 2010-05-20 21:49:32 EDT
The java.com test shows that java is installed, but following the link to see whether it is working shows that it is not. The suggestions given there do not get it working, nor do they make it show up in about:plugins. Also, running mozilla-plugin-config -i (leaving the fedora default /etc/sysconfig/nspluginwrapper intact) does not change the symptoms. No java in firefox. Conversely, konqueror does indeed show java with this standard installation and setup.

You appear to have the updates-testing version of java-1.6.0-openjdk. The version in F13 stable is 188.8.131.52-37.b17.fc13.x86_64. Try "yum downgrade java-1.6.0-openjdk" to downgrade to this version (which works for me on a clean F13 x86_64 install).
Comment 3 Peter Gückel 2010-06-10 21:08:21 EDT
I upgraded to java-1.6.0-openjdk-184.108.40.206-39.b18.fc13.x86_64, which is in updates (not updates-testing) and the problem persists. No java plugin in firefox.
Comment 4 Peter Gückel 2010-06-10 21:29:49 EDT
(In reply to comment #3) After updating, I checked /usr/lib64/mozilla/plugins and I see that there is a link libjavaplugin.so that points to /etc/alternatives/libjavaplugin.so.x86_64, which is also a link that points to /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/lib/amd64/IcedTeaNPPlugin.so, which does not exist. There is a IcedTeaPlugin.so (no NP) there, however. Should the link point there? OK, I ran: alternatives --remove libjavaplugin.so.x86_64 /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/lib/amd64/IcedTeaNPPlugin.so and now the link was automatically shifted (alternatives reports that "status is auto") to /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/lib/amd64/IcedTeaPlugin.so. I now have an icedtea plugin in firefox. The link that is provided by the java openjdk-plugin package is wrong.
Comment 5 Andre Robatino 2010-06-11 00:43:25 EDT
I now have the same problem (no Java plugin in Firefox) as you, even though I didn't before. I seem to have the same problem (wrong links). Not being familiar with alternatives, can you check if there is 100% CPU usage while running Java applets, as reported in bug #592553?
Comment 7 Andre Robatino 2010-06-11 02:12:28 EDT
I fixed the alternatives link and the 100% CPU usage is still there. Will downgrade to the original release version until a good version is released.

Not being > familiar with alternatives, can you check if there is 100% CPU usage while > running Java applets, as reported in bug #592553? No, there is no 100% java problem. When viewing a java web page in firefox, the browser uses at most 2% of processor power and X sometimes jumps from 2% to 4%. That is all.
Comment 9 Andre Robatino 2010-06-15 12:19:55 EDT
The latest version 220.127.116.11-41.b18.fc13.x86_64 is working properly for me (link fixed, 100% CPU gone).
Comment 10 Peter Gückel 2010-07-09 18:12:13 EDT
I am now on java-1.6.0-openjdk-18.104.22.168-41.b18.fc13.x86_64 and all seems well.
