If you are into AOP (Aspect Oriented Programming), you may be able to
create an Aspect to do this for you. I don't know enough about it to give
you any explanation of how to use AOP, but you could take a look at a
promising new AOP project based on dynamic proxies....

Hi Jake,
Thanks alot jake. My application now exceeds 1 million lines of code and
has so many printStacktraces in my application. I was searching for hack if
I could log them magically. Yesterday I browsed for this in the archives but
coudn't find any. Just to confirm my finding I posted it. Anyhow thanks a
lot. I will start looking for printStacktraces occurences and will changes
them manually.

Do you mean will Log4j provide some sort of magic to display exceptions
that happen? Well, no. You have to log the exception yourself, just like
anything else you log.
logger.debug("Boom! An exception", e);
Log4j doesn't handle your exceptions for you, but provides a way to view
the ones you catch in a log. Hope I didn't completely miss the point on
that one. If I did, please re-explain what you are trying to get at.
