Calling Jython code from Java

[Raja]

I have a java class thats trying to call something in python. This
works fine when i do a jythonc on the python script.
When i call another python script from the __init__ of my called
python script, things go bad.i get this message
AttributeError: class 'configuration' has no attribute
'configuration'
when calling the constructor.
This is my python script thats called by the java class
testconfig.py
=============
import configuration
import java.lang

class testconfig(java .lang.Object):

def __init__(self):
"""@sig public testconfig()"""
self._cfg = configuration.c onfiguration("/sources/jmxproto")

def getValue(self, whatVar):
pass

and the other script is configuration.p y
class configuration:

def __init__(self, runtimeDir=None ):
"""@sig public configuration(j ava.lang.String dir)"""
""" Some code in here """

When i call testconfig.py, i get the error mentioned above. Any clues?

Thanks
Raja

In Python, you just use the class name to create instances.

So I think that perhaps:

self._cfg = configuration.c onfiguration("/sources/jmxproto")

Should be:

self._cfg = configuration("/sources/jmxproto")

IIRC the "@sig" declaration only comes into play when attempting to use
the class from *Java* code. That's why there is no "configurat ion"
attribute.
