Using inspect.py in Jython

[rajasankar]

Hi,

I am using Jython based application and trying to use inspect.py in the python files.

Here is my code

import inspect,os,sys,pprint,imp
def handle_stackframe_without_leak(getframe):
    frame = inspect.currentframe()
    try:
        function = inspect.getframeinfo(getframe)
        print inspect.getargvalues(getframe)
    finally:
        del frame
#
def raja(a):
    handle_stackframe_without_leak(inspect.currentframe())
    print a
#
def callraja():
    handle_stackframe_without_leak(inspect.currentframe())
    raja("raja@ad.com")
#
callraja()
raja("raja@ad.com")

When I execute this using python.exe, there are no issues. However, when I use this inside the Jython app, I've received errors.

I've tried to find info about this error without success.

Any help will be appreciated.
