show class location?

I'm getting a NoSuchMethodError, yet the source shows the method, as does
the
decompiled class embedded in the jar that I think it comes from.  But I
guess
not.  Is there a way to display the class location on the file system?

3.4
jdk 1.5.0_06
win2K SP5

Thanks,

In CS we don't have a lot of formal models to guide us, as in engineering
or other science. Much of CS is entirely ad-hoc. However we do have a sound
and complete model for data storage (relational model) and hardly anyone
uses it. It boggles my mind. Do people not *want* their programs to work
predictably?
