Bug Description

When installing Java 6 in Hardy alpha 6, the browser plugin is not installed properly. I have sun-java-6 installed and all related packages except docs. When I go to a page in Firefox that uses the Java plugin, I receive a prompt asking to install an available plugin - I select "The Java(TM) Plug-in, Java SE 6" and click Next. Then I receive prompt saying "Package 'sun-java6-plugin' is already installed". After clicking finish, closing the browser and reopening Firefox, the plugin is still not installed properly. I've also run "sudo update-java-alternatives -s sun-java-6" and one message I receive is "No alternatives for firefox-plugins-javaplugin.so".

OK, I figured this one out finally, looks like under firefox 3 plugins a symlink is missing.

What worked for me:
alex-mayorga@inspiron-1501:/usr/lib/firefox-3.0b3/plugins$ sudo ln -s /usr/lib/jvm/java-6-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so

Before:
alex-mayorga@inspiron-1501:/usr/lib/firefox-3.0b3/plugins$ ls -la
total 8
drwxr-xr-x 2 root root 4096 2008-01-02 17:09 .
drwxr-xr-x 5 root root 4096 2008-01-17 22:55 ..

After:
alex-mayorga@inspiron-1501:/usr/lib/firefox-3.0b3/plugins$ ls -la
total 12
drwxr-xr-x 2 root root 4096 2008-03-13 16:29 .
drwxr-xr-x 5 root root 4096 2008-01-17 22:55 ..
lrwxrwxrwx 1 root root 64 2008-03-13 16:29 libjavaplugin_oji.so -> /usr/lib/jvm/java-6-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so

Looks like the Java plugin is not symlinked under Firefox 3.

Still a problem with Firefox 3 Beta 4. The above fix works though.

Also worthy to note that the Java plugin is installed to /usr/lib/firefox/plugins/ but Firefox doesn't seem to check that location. Probably will when the stable version is released.
