Same problem on Jaunty 32-bit. sun-java6-plugin installs, Sun Java the default Java (in update- alternatives), but Firefox 3.6.8 about:plugins shows no plugin installed.
Unlike BjA, the fix for me was to symlink the separate libnpjp2.so in /usr/lib/firefox/plugins *and* /usr/lib/mozilla/plugins. In my build, only libjavaplugin.so was there, correctly symlinked to the /usr/lib/jvm path. Is this something that's broken with the recent upgrade of Firefox to 3.6 on older Ubuntu releases (such as Jaunty)?? ls -al /usr/lib/mozilla/plugins [includes only /usr/lib/mozilla/plugins/libjavaplugin.so -> /etc/alternatives/mozilla-javaplugin.so] ls -al /usr/lib/mozilla/plugins [includes only /usr/lib/mozilla/plugins/libjavaplugin.so -> /etc/alternatives/mozilla-javaplugin.so] cd /usr/lib/mozilla/plugins sudo ln -s /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so cd /usr/lib/firefox/plugins sudo ln -s /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so [Test Java plugin] firefox http://www.java.com/en/download/installed.jsp -- Java browser plug-in does not work https://bugs.launchpad.net/bugs/424971 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
