How do I rethrow an exception that contains information about an original exception?

exception, python, python-2.2, wlst

Solution

I hope I got the question right.

I'm not sure about Python 2.2 specifics, but this says you can handle exceptions the same way it's done in more recent versions:

try:
    do_stuff()
except ErrorToCatch, e:
    raise ExceptionToThrow(e)

Or maybe the last line should be `raise ExceptionToThrow(str(e))`. That depends on how your exception is defined. Example:

try:
    raise TypeError('foo')
except TypeError, t:
    raise ValueError(t)

This raises `ValueError('foo')`.

Hope it helps :)

Problem

So I basically have to isolate 2 layers of the application from one another by exceptions. I have this WLST 12c script (python 2.2), that goes like ``` try: something something... except java.lang.UnsuportedOpperationException, (a, b): pass except java.lang.reflect.UndeclaredThrowableException, (a, b): pass ``` I'd like to be able to re-raise one of my own types of exception, that contains a message about what caused the previous exception (and no, i don't know what the `a` and `b` parameters are, but i'm guessing one of them should be the exception description). I'm a java guy myself, so i am looking forward to something like ``` try { something something... } catch (Exception e) { throw new RuntimeException(e, "something horrible happened"); } ```
