jython.jar must be in your compile classpath.

Thanks! The code is all set up now, but I am still having a bit of a problem
- it can't find org.python.core or org.python.util.PythonInterpreter. I'm
compiling using javac in a Mac OS X terminal, and both the java files and
the jythonRelease_2_2alpha1 folder are both in the home directory. I tried
compiling the example you pointed me to, from its default position in the
Jython file heirarchy, and it gave the same errors. I installed Jython
fully, etc. and I'm not sure how to proceed. Help would be much appreciated.

Hi all,
I know nothing whatsoever about Python. I just downloaded Jython oin the
recommendation of someone in some forum responding to a question about
how to evaluate strings from Java - it turns out that the standaard
libraries provide no real way to do this.
I have a very simple situation - I have a string with a basic
mathmatical expression, like "3+45*2" and I want to store it's value in
an int from a Java program.
This example shows how to do what you want:

I'm not sure but I think the returned PyObject will actually be a
PyInteger and you can call getValue() on it to get the result.
You should know that eval() is a security hole that leaves you open to
denial-of-service attacks and probably data loss. Don't eval() strings
from an untrusted source.
