Um, interest in using Chain in 1.3 is not even close to the same thing
as interest in Jericho. ;-) While some people may be interested in
both, it's certainly not safe to assume that the former implies the
latter.
Jericho is a proposal for the Struts 2.0 revolution, as envisioned by
Ted almost a year ago. As such, it is an alternative to Shale. Neither
of these proposals have backwards compatibility as a primary concern;
rather, that would be a "nice to have".
We are currently discussing the use of Commons Chain in the Struts 1.x
family, starting with 1.3. The idea is that we would replace the
current request processor with the one from struts-chain, providing a
much better means for people to customise the request processing flow.

I'm afraid I don't really understand what you are asking for. Are you
just asking for how you can compile Java code from Java code? If
that's it, then I believe the Java compiler has a standard API that
you can call, although I don't know off the top of my head where that
is documented. Someone else might know.
