[Jython-dev] Precompiling code in jython

[Philip W. <phi...@to...>]

First of all cool product. I like the concept alot.

We are looking at creating a rules engine based
on Jython embedded in java.  I played with the PythonInterpreter example
code and got it to work but it may be too slow if you have to do=20
this each time.  What I would like to know how to do is the following:


class {
    init(){
        interpreter =3D new PythonInterpreter();
        interpreter.setJythonParameters(JavaEventProxy proxy);
        interpreter.precompile(JythonCode);
     }

    Object event(Event e){
        proxy.setEvent(e);
        if (jythonCode.changed()){
            interpreter.precompile(JythonCode);
        }
        interpreter.execute();
        return interpreter.get("");
    }

I don't see how to do the "precompile" stage. I tried using the eval =
funtion but
it kept throwing an exception. =20

Do you have or can point me to an example which uses the eval correctly =
or
does the above it would be greatly appreciated.
