[Jython-users] traceback in jython

[Barry H. <b.h...@sc...>]

Hi 

I'd like to do something like the following in jython

import traceback
try:
#...
except:
	traceback.print_exc()

But the module traceback doesn't seem to be included in jython. Instead I use
something like

import sys
try:
#...
except Exception, detail:
                print  sys.exc_info()[0] , detail
                print(sys.exc_info()[2]).dumpStack()

But is there a better way? ie, is there an equivalent to traceback in jython ?

cheers
Barry

Module traceback works fine for me under jython 2.0.
The other day I was bitten by this:

import sys. traceback

which gives a somewhat confusing error message about
traceback module not found, or something like that.
The fix was to use a comma instead of a dot.
I hope your case is about as simple. When not do a

import sys
print sys.path

and check that the traceback.py module is on the path (in
"jythondir"/Lib IIRC)

Good luck,
Ype

Thanks for that. It seems I was using a CVS version of jython, which didn't
include traceback. I've switched to the 2.0 release version and all seems well.

cheers
