My report listed my java plugin as coming from a version I downloaded from Sun while trying different ways to fix the problem. When I redirect my java plugin in /etc/alternatives I have:
giovare:/home/ted# ls -l /etc/alternatives/*iceweasel* lrwxrwxrwx 1 root root 73 2009-12-28 17:13 /etc/alternatives/iceweasel-javaplugin.so -> /usr/lib/jvm/java-6-sun-1.6.0.16/jre/plugin/i386/ns7/libjavaplugin_oji.so Now Iceweasel reports my plugin as 1.6.0 16-b01. I have two computers, both running squeeze that I have this problem on. Java worked on both of them until I ran update-alternatives after downloading sun-java6-sdk (there is a readme file that advises people to do this included with the package). Both computers now have nonfunctioning java plugins in iceweasel.
