I'm trying to get the java plugin working with Mozilla Firefox running under Fedora 3. I believed the Java Runtime Environment 5.0 has been installed successfully in /usr/java/jrel.5.0. I put a link to the file /usr/java/jre1.5.0/plugin/i386/ns7/libjavaplugin_oji.so in /usr/lib/mozilla/plugins. Software I'm running from a website needs Java -- but I keep getting the message that J2SE50 needs to be manually installed. I can't tell if this is some problem at this website or that I haven't installed Java correctly. Is there anything obvious I've done wrong here -- or an easy way to check if I've done things right? I was thinking of trying some other website using Java in an obvious way so that if the plugin wasn't installed correctly I could tell. Any suggestions for troubleshooting this would be most appreciated.
