We are planning to start work on a compiler after JavaOne, both for performance reasons and to support extending Java classes in Ruby (which we can't do now because we use java.lang.reflect.Proxy which only works on interfaces). We may also have an intermediate compiler for a short-term performance gain, and we may be able to tackle the class extension issue earlier than compilation. Fun stuff!

I saw in the limitations document that the reason ...

I saw in the limitations document that the reason you can't extend with Ruby in runtime and consume the descendant with Java because you don't have a compiler.

This might be over my head, but if you did have a compiler, wouldn't that make JRuby an excellent platform for testing Ruby code? An intriguing possibility.

Or is this compiler a pie-in-the-sky requirement in the first place?

That is exactly the deployment scenario we're shooting for. We already have some prototype code of a "CGI Servlet" that provides a webapp-based entry point into Rails, and it works as well as an FCGI option (with the caveat that we're still much slower than C Ruby). Eventually, we want to be able to WAR up an entire Rails app + libraries, shove it into a webapp container, and off it goes. It will happen sooner than you think!

I know this is probably too forward thinking and/or pretentious, but do you think that eventually Rails apps could be deployed on Tomcat packaged as WAR files?
