Maybe, but I don't think this was ever properly implemented.
There's some code inplace for genberating a jnlp file but I belive there
were problems packing the code.

It didn't work. :)

You would have to look at the JNLP specs, I think, to see if the files
need packaging in a specific way. I last looked at this maybe two years
ago, and it never reliably worked for me. I didn't have a compelling
need for it so I didn't continue.
If you want to take a stab look at the rawr code that invokes the jar
command to see if there's a better way to assemble the final package.
This may also help:

Plus the rawr source has some specs for testing jnlp if there's ever
proper code to create the package.
