I am not sure where to start debugging here and I also don't know exactly when it stopped working (it has worked once; but I haven't perhaps really needed Java applets for some months and now when I needed them, I recognised for the first time that it is not working anymore). Some sites like http://www.jgiesen.de/javascript/Beispiele/Hallo/Hallo-Applet.html just show me a "click here to install the missing plugin" or some other pages (some local page where I want to try out a java applet) just shows nothing. I haven't made any special configurations in Firefox. I would expect that it just works (as it has earlier). Java is of course activated in the options (but that was the default). When I type "about:config" and filter for "java", no option was changed (related to Java), they have all the default values.

az@acompneu ~ $ java-config-1 -L The following JDKs are available for generation-1: *) Sun JDK 1.4.2.18 [sun-jdk-1.4.2.18] az@acompneu ~ $ java-config-2 -L The following VMs are available for generation-2: *) Sun JDK 1.4.2.18 [sun-jdk-1.4] 2) Sun JDK 1.6.0.07 [sun-jdk-1.6] But I also have tried to change the generation-2 VM to Sun JDK 1.6 but it doesn't change anything. In Eclipse, I can start my Java applet without problems. In Opera, it also works (though they are displayed in kind of "old-style", with darker background, non-alaising font and the buttons look different; in Eclipse, they just show up normally, but I think that Eclipse also uses JRE 1.6 and Opera uses 1.4).
When I start Firefox on console, I don't get any messages. As I am not sure how to call the Java console in Firefox (I just don't see the menu entry for it, I am not sure where it should be), I cannot get any error message and thus just no hint where the problem could be.
I would think that perhaps java-check-environment could help me out, but it just says that everything is ok (it even congratulates me): az@acompneu ~ $ java-check-environment * === Java Environment Checker === * The purpose of this script is to check the sanity of your Java Environment. * We have significantly changed and improved the way Java is handled in many * respects. * Please refer to our upgrade guide for details: * http://www.gentoo.org/proj/en/java/java-upgrade.xml * Checking fastjar ...

When I look at the stuff in "about:config", I am a bit wondering about these: java.default_java_location_others = /usr/java java.global_java_version_file = /etc/.java/versions Both paths/files just don't exist. But these are the default values of Firefox. Do I have to change something there? Why are these values not correct by default? Then I am wondering about this: java.java_plugin_library_name = javaplugin_oji Where does it try to search for it? In the above (non-existing) paths? Or how can I check in which paths it searchs for this file?
Ok, I was just searching a bit around through my file system for some paths where perhaps Firefox could search for plugins (I still don't know how to get a list of these paths). I get to the path /opt/mozilla/plugins and I am wondering about this: az@acompneu ~ $ ls -la /opt/mozilla/plugins/ total 1329 drwxr-xr-x 2 root root 1408 2008-10-22 19:00 . drwxr-xr-x 3 root root 72 2004-09-26 06:23 .. lrwxrwxrwx 1 root root 59 2006-07-29 01:47 javaplugin.so -> /usr/share/java-config-2/nsplugin/sun-jdk-1.5-javaplugin.so ... This is an invalid link, the file /usr/share/java-config-2/nsplugin/sun-jdk-1.5-javaplugin.so does not exist. Could that be the problem?

Ok, I solved it! After reemerging sun-jdk-1.6, it workes. This is after I removed this bad link. And what I see from the output, it seems that because I have deleted the link, the ebuild just creates a new link, but this time a valid one. ... --- replaced dir /opt --- replaced obj /etc/revdep-rebuild/61-sun-jdk-1.6 --- replaced dir /etc/revdep-rebuild --- replaced dir /etc * Updating desktop mime database ... >>> Original instance of package unmerged safely. * JREs and 1.5+ JDKs are not supported for use with generation-1. * This is because generation-1 is only for use for building packages. * Only generation-2 should be used by end-users, * where all JREs and JDKs will be available * No system nsplugin currently set. * Setting nsplugin to sun-jdk-1.6... * You can change nsplugin with eselect java-nsplugin. * Updating desktop mime database ... * Please reinstall eclipse-sdk if you have it installed and want * workaround for bug #215150. >>> Auto-cleaning packages... >>> No outdated packages were found on your system. * Messages for package dev-java/sun-jdk-1.6.0.07: ... I didn't know that there is something like eselect java-nsplugin. I probably had the JDK 1.5 installed earlier but after unmerging it, it did not fix this link. That is what this whole bug is about: If unmerging a JRE/JDK and that makes the plugin.so-link invalid, it should reset it to a valid JRE/JDK if possible.
