title: Open source Web based Java compiler
body: <p>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. </p>
  
  <p>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.</p>
  
  <p>My questions are:</p>
  
  <ol>
  <li><p>Are there any such open source java
  compiler/executor services available
  which can be used?</p></li>
  <li><p>Is anyone interested to work on such
  project (in case there isnt any)?</p></li>
  </ol>
  
  <p>EDIT: 
  I am planning to use Compiler in java and Beanshell. Any better solutions ?</p>
