RE: [Jython-users] super newbie question

thank you Jeff, that did work dandy.

but now a different problem; perhaps you or someone can help me with it.
i used jythonc to turn the class into a .class and put it in a directory
that has some other .class examples for the system I'm using. I then used
ant to build the examples.jar file, and that class was apparantly included
(I say apparantly because the `sum` of examples.jar was different when i
had the file in question in that directory). but the following happens:

createAgent org.tagents.examples.AgentEx1 ===> works fine
createAgent org.tagents.examples.AgentPy ====> gives the following:

(a short note: I see that the code i'm using defines its own class
loader; I understand that that could be the problem. I just thought I
would check to see if I'm missing anything on the jython side before
pursuing that route)

java.lang.NoClassDefFoundError: org/tagents/examples/AgentPy (wrong
name: AgentPy)
