Is it possible to install the sun-java6-plugin from jaunty in intrepid?

[Chris G]

I have a need for the 'real' Sun Java6 plugin for my Firefox on
Intrepid (xubuntu 8.10).  It's not yet available for Intrepid but
there is a Jaunty (9.04) version.

Can anyone tell me if I can get the Jaunty version installed in
Intrepid, or can I do a manual install of the Sun JRE in Intrepid and
get what I want?
