Tracing in Java

[steve]

I have a java app which I'm supposed to maintain. Is there any way I can
find out what methods,class the
application uses from start to end. I don't like the idea of looking at the
code as it will take too much of
my time.

Jet has a feature called JetPerfect that will collect a list of
classes actually used during execution. However, that is only
available in the professional edition. See

You could write your own classloader that dumped the name of each
class to a file at is loads. See

Most profiling tools will do tracing

If you are willing to learn Aspect Oriented Programing, you can create
an aspect that writes to a log file before it enters a message...

Indeed this seems to be the only known use for AOP. <GD&R>
