Hi,

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

Here is my code
Expand|Select|Wrap|Line Numbers
  1. import inspect,os,sys,pprint,imp
  2. def handle_stackframe_without_leak(getframe):
  3.     frame = inspect.currentframe()
  4.     try:
  5.         function = inspect.getframeinfo(getframe)
  6.         print inspect.getargvalues(getframe)
  7.     finally:
  8.         del frame
  9. #
  10. def raja(a):
  11.     handle_stackframe_without_leak(inspect.currentframe())
  12.     print a
  13. #
  14. def callraja():
  15.     handle_stackframe_without_leak(inspect.currentframe())
  16.     raja("raja@ad.com")
  17. #
  18. callraja()
  19. raja("raja@ad.com")
  20.  
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.
