If you're using Netscape or Mozilla, type in the address bar
You should see a list of all the plugins that are installed. If you do not see anything about java, it means that Netscape/Mozilla doesn't know where to find it...
If you say you succesfully installed java vm from sun, you must add a symlink to the module you plan to use...
Let's say you installed JRE in /opt/jre. In its subdirectory, there's a plugin/i386 dir. You can then select your current version of netscape (usually ns610). In this directory (/opt/jre/plugin/i386/ns610) is a file with the *.so extension.
Now move to your netscape/mozilla directory
and issue this command:
ln -s /opt/jre/plugin/i386/ns610/libjavaplugin-oji.so /usr/lib/netscape/plugins/libjavaplugin-oji.so
You may have to change names to fit your current installation. The syntax is this:
ln -s /dir/where/you/installed/java/
I hope you undestood. You can verify if it works by restarting netscape/mozilla and typing in the address bar
Now you should be able to see x-java-vm in the list.
Note... It works better with Netscape than with Mozilla.
