You must find out where you're installing Mozilla (usually
/usr/lib/mozilla-version).  Don't assume that /usr/lib/mozilla is where
it went.  Often, /usr/lib/mozilla is a symbolic link to where the actual
stuff lives.  For example:

[root at prophead root]# ls -ld /usr/lib/moz*
lrwxrwxrwx    1 root     root           11 Nov 10 12:09 /usr/lib/mozilla 
-> mozilla-1.5
drwxr-xr-x    9 root     root         4096 Aug 15  2003 
/usr/lib/mozilla-1.2.1
drwxr-xr-x    9 root     root         4096 Aug 19  2003 /usr/lib/mozilla-1.4
drwxr-xr-x    9 root     root         4096 Nov 17 09:48 /usr/lib/mozilla-1.5

As you can see, /usr/lib/mozilla is a symlink to /usr/lib/mozilla-1.5.

Regardless, you must get to the real install directory (in the above
case, /usr/lib/mozilla-1.5) and create a symbolic link from that
directory's "/plugins" directory to your Java binary.  Again, an
example:

[root at prophead mozilla-1.5]# cd /usr/lib/mozilla-1.5/plugins
[root at prophead plugins]# ls -l
total 1960
-rwxr-xr-x    1 root     root          856 Nov 10 14:38 flashplayer.xpt
-rwxr-xr-x    1 root     root      1470464 Nov 10 14:38 libflashplayer.so
lrwxrwxrwx    1 root     root           79 Nov 19 13:37 
libjavaplugin_oji.so ->
/usr/local/j2sdk_nb/j2sdk1.4.2/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so

That's the link that needs to be created (the libjavaplugin_oji.so one).
Every time you install a new Mozilla, you need to fix that.
