You could use ALF[1] to trace method invocations. ALF allows you to
specify classes and packages to trace. For more selective evaluation you
could easily write a script that massages the output, or at least selects
only those lines that contain the method you want to inspect. This way
you don't get a graphical output but you can recognize the calling tree
via indention.

Another option is to use doxygen [2] which generates a very nice,
hyperlinked documentation much like JavaDoc but with additional graphical
class diagrams (including dependencies), that can also be navigated. And
the source code is included and linked.

Re: Tool for Visualizing external / internal metod calls

Thank you for the response.

AFL only seems to trace runtime invocations. As I want to trace mainly EJB:s
running within a container this would be a bit awkward. Apart from that it
does seem to feature just about the things I'm looking for. Do you know of
any tools that can generate the same information from source-files and not
runtime-invocation ?

Yours,

Linus

The DMS Software Reengineering Toolkit could probably do this relatively
easily.
It has a full Java front end, builds compiler data structures (ASTs) for an
entire
system of software with full name and type resolution.
From there, it can be customized to extract all kinds of interesting
information,
including what you are requesting. One example of extracted information
is a full cross reference according to the language rules; see our
Java Source Code Browser (and especially the example of it) at
http://www.semdesigns.com/Products/F...aHTMLizer.html.
