>>We have integrated Spring, Jetty, and Velocity all on a SBC running 
embedded Linux. We compiled the Spring et al. under gcj 3.3 to
native xscale object code. It works beautifully - it's fast and 
reliable, with all of the Spring functionality intact.
The bad news is that it took a fair amount of work. Mostly little GCJ 
incompatibility nits. But I think that things are vastly better (as far
as compatibility goes) with more recent versions of GCJ. I would try 
GCJ 4.0 in particular, but the latest in the 3.4 series is also a good
bet.
JSP is potentially a big problem, although it might work. Remember that 
JSP uses the JDK to compile servlets, one for each JSP page. 
Hard to believe, but that's how it works. For this reason we avoid JSP 
like the plague, and use Velocity. Velocity is much easier to use,
much faster, and results in better, more easily understood dynamic 
pages. Also, you should seriously consider using Spring Web MVC. 
It's much better and much easier to use than Struts. The J2EE pundits 
have shown that Spring Web MVC mops the floor with Struts.
