Question

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");
}

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 🙂
