I don't know that it is. What I'm interested in doing is starting a Python interpreter in Java, then occasionally calling into it to exec some Python code. It would be great if it could also eval a Python expression and return the unicode() of the result. I'd like to see if I can add that functionality to PythonVM. Then I'll worry about Tomcat, where I imagine I'll have to do just what you've already done. > If what you say is true then how is that different from what Roman is > doing with JCC and Python's subprocessing module ? I don't know that it is. I use the subprocess module a lot in UpLib, too. Bill
