okay. gonna assume you unpacked the *.bin and installed the java rpm. do this:
1. cd /usr/lib/mozilla-1.1/plugins
2. rm -f libjavaplugin*.so
3. ln -s /usr/java/j2re1.4.2_02/plugin/i386/ns610/libjavaplugin_oji.so
run mozilla. type in the address bar: about
you should see java listed in there.
some things to make sure of though.
in #1 make sure that that's the correct directory for your version of mozilla. just look in /usr/lib and look at all the mozilla directories.
also run mozilla and do Help > About to make sure of the version of mozilla when you run it.
