Re: [Jython-users] How to access a java program from python

[David H. <Dav...@sa...>]

Yes, you can create a module that can be run either with Python or =
Jython. The trick is to make sure that you only import Python modules =
and not Java classes.

If you have "from java.anything import ..." then you know it will not =
work with Python, because Python cannot import any Java classes. =
Instead, for random numbers, try this:

import random
print random.random()

Most of the standard Python 2.2 modules documented here will run in both =
Jython and Python:

Hope this helps,
David H

Hello,

Yes, I tried both (p and j, with j works).  So my question was, if is it =
possible to call a jython application using python command, or to create =
a jython program as python module?.  Sorry if this question is too naive =
for this group, I am a beginner in jython and python.

Thanks,

Lorena Carlo
