Hi Jason,
I don't think that log4j is the right tool for this. You would need to add a log
statement at the beginning and end of each method. It could be done, yes, but I would
not recommend it, unless of course you have these statements in the code already. Even
then, having a log method at the beginning and end of each method is costly in terms
of performance.
You want a tool that does the analysis, spits some useful output without being
intrusive.
You probably want to look at code that automates the process. For example, see
www.aspectj.org. I am sure there are other tools. I just don't know them. Cheers, Ceki
