Does anyone know / has experience with a serverside Javascript solution for Apache? Maybe compiles to servlets and has access to the Java framework. Much like Jython? I know Javascript, I know Java and I'm willing to learn Jython, that is how much I dislike JSP. Too much work, still not a clean cut between presentation and logic tier.

I'm aware of Rhino, but this is a generic Javascript implementation in Java. The solution I'm looking for is probably Rhino based but serverside web specific!
