[Jython-users] ProxyMaker not found?

[Peter B. <bri...@ma...>]

Hi!
I've got another problem with some code that works fine when interpreted
with jython but breaks down when compiled with jythonc.

I've narrowed the problem down to the following situation. We need two
modules, say init.py and main.py.

----------------------------------------------------------------------
init.py:

import java

cl=java.lang.Object

----------------------------------------------------------------------
main.py

import init

class eggs(init.cl):
	pass

print eggs()

----------------------------------------------------------------------

The idea is to derive a class from another class that's determined in
a different module. The jython run gives the desired result:

	[brinkman@c1176023-a test]$ jython main.py
	<__main__.eggs instance at -1244487580>

However, when I compile it with

	jythonc --core --jar test.jar main.py

and run it with

	java -jar test.jar


I get the following stack trace:

It appears that the problem only occurs when init.cl is a java class, such
as java.lang.Object or java.awt.Frame or so. Python classes seem to work
fine, both interpreted and compiled.
I would appreciate any ideas regarding this problem.
Thanks,
