Open source Web based Java compiler

Question

I want to create a web based java tutorials kind of project which involves jquery, css, jsp, springs etc ., so I actually want to practice these technologies resulting a good product. The content of this tutorial can be edited by any user and rated by clients according to the chapter etc., I have few such ideas.

One primary idea being have a web based compiler and executor . Similar to w3schools. I know its difficult for a compiler of server side technology on a browser.

My questions are:

1. Are there any such open source java compiler/executor services available which can be used?

2. Is anyone interested to work on such project (in case there isnt any)?

EDIT: I am planning to use Compiler in java and Beanshell. Any better solutions ?
