Then, as Leigh said, you need to create a symbolic link into your firefox plugin directory to point to the java library. In order to do this, you need to find your firefox plugin directory (/usr/lib/firefox-1.5.0.7/plugins in Fedora) and the path you installed java to (/usr/java/jre1.5.0_06/plugin/i386/ns7/libjavaplugin_oji.so on my Fedora box). Then, as root, cd to the firefox plugin directory and create the symbolic link there:
Code:
cd /usr/lib/firefox-1.5.0.7/plugins
ln -s /usr/java/jre1.5.0_06/plugin/i386/ns7/libjavaplugin_oji.so ./libjavaplugin_oji.so
