Getting Java Plugins to Run with Mozilla in RH 9

[rab]

I'm not sure why java is so problematic in RH Linux. I've had it running 
in the past. I have:

[root at tangent plugins]# pwd
/usr/lib/mozilla/plugins
[root at tangent plugins]# ls -l
total 168
lrwxrwxrwx    1 root     root           37 Dec 20 13:22 flashplayer.xpt 
-> /usr/lib/flash-plugin/flashplayer.xpt
lrwxrwxrwx    1 root     root           39 Dec 20 13:22 
libflashplayer.so -> /usr/lib/flash-plugin/libflashplayer.so
lrwxrwxrwx    1 root     root           61 Mar  6 19:14 
libjavaplugin_oji.so -> 
/usr/java/j2re1.4.1_01/plugin/i386/ns610/libjavaplugin_oji.so
-rwxr-xr-x    1 root     root        22176 Jan 25  2003 plugger.so
-r--r--r--    1 root     root         4139 Jan  6  2003 raclass.zip
-r-xr-xr-x    1 root     root       129088 Jan  6  2003 rpnp.so

How can I get Mozilla to run Java apps? Every time I install a new 
version of Mozilla, java plugins stop working.
