You might be able to compile the Sun javax.comm classes. You would do
this by compiling each .class file separately and then making a `.so'
by linking the results. Then you would link this .so into your final
application.
This might or might not work. I don't usually try stuff like this.
If the Sun code has native methods then make sure to compile with
`-fjni'.
There might be a free version of javax.comm around. I have never
looked. There isn't one in libgcj, as you noticed. I don't think
anybody is working on it either.
If there is a free one, and you try it, and gcj can't compile it, then
we would be very interested in whatever bugs you find. I think it is
important that gcj be able to compile free Java applications.
