Sun-Java-Plugin for Firefox doesn't work

[slabo]

Ubuntu 11.04 amd64 here. I installed sun-java6-bin, sun-java6-jre and sun-java6-plugin and checked via update-alternatives that they are used. On first glance, it looks alright: java -version says i'm using 6.0_26-b03, Firefox says on the about:plugin-page that i'm using the sun-java plugin, but the Java test-page doesn't work. Also, the online-application i installed this for doesn't work. jcontrol crashes.

Also, my "Sun Java Plugin Control"-Application doesn't work.

The weird thing is that i installed Sun Java yesterday, and it worked. (Can only say this for the online-application, though.) Today after booting my computer anew, it didn't work. Since then, i deinstalled openjdk and reinstalled it (since i need java) and also reinstalled sun-java, but can't get it to run.

Any ideas would be greatly appreciated.

Did you install Java from the PPA?

Okay, so i tried it, and the Plugin is, as before, listed on "about:plugins", but it doesn't work, according to the Java test-page. Also, when trying to start the Control Panel i get:

"java -version" works.

Make sure you have the restricted extras installed.
