Hi Tomcat Developers!
I'm contributor in the Apache Software Foundation's GHOP Contest and
working on issue
19(http://code.google.com/p/google-highly-open-participation-asf/issues/detail?id=19)
I've plan to write scripts that generate tomcat dependency for jars
and classes and submit it to you.
Can you explain how you would like to see it and who can help me with
details about that task?

With regards,Sergey

Take a look at UMLGraph... http://www.umlgraph.org/

It can generate GraphViz diagram specifications, which you can then
process into images.

Here's an example of the kind of thing it can do:

I've generated some graphs and dot files but graphviz can't generate
graph for classes deps.
I'll try to resolve this and submit some code.

This entire list (dev@tomcat.apache.org) is open to you and we can
help you.  Please subscribe to the list by following the directions at
http://tomcat.apache.org/lists.html#tomcat-dev, if you haven't
already.

As for the format of the scripts and the resulting output: it's mostly
up to you.  We run all our scripts on Linux, and we use Ant for
building Tomcat.  So an Ant build.xml file that generates the
dependency graphs would be great.

Personally, I am a big fan of GraphViz (http://www.graphviz.org/) for
this sort of task.  I think it's a good candidate for three reasons.
First, it's free and easy to use.  Second, it's designed for and thus
it's excellent at displaying very large graphs with many dependencies.
 Third, it lets you separate the graph structure from the output.
That way your Ant script can just output the .dot file that GraphViz
takes as an input.

However, that's just one tool.  Like I said, the choice is yours.  If
you prefer another tool, that's fine.

Like Yoav said, tool you choose is irrelevant.
However, it would be good to be reproduceable.
Also, finding things like multiple classes inside
different jars (if any) and jar manifest
(particularly versions) tracking would be cool to have.
