java in mozilla

Is it possible, and if yes, how can I get java applet work in Mozilla ?

I have J9/J9plugin which work well with Voyager. But no way to have it
work in Mozilla. (no applet, no java console)

It seems that Mozilla requires the Sun JRE, and a symbolic link has to be
done from a .so to the Mozilla plugin directory. But the files are
different for J9.

Is there a way to tell Mozilla that J9 is my JRE, and to use it ?
