Tools for rapidly understanding large java projects

[Nate Sanders]

What are the best tools for rapidly gaining understanding of large java projects? For C stuff, I've used Gnu Global/htags to produce hyperlinked sources. In addition, I've used some static call graph analyzers and also written some perl code to insert meaningful stuff into the source to produce logs for dynamic analysis.

What, if anything, do people often use? Are there good automated UML/class hierarchy/etc diagram makers? Static call graph analyzers, etc?

Thanks,
Nate

Hi Nate,

I can't speak from experience, but if you're using eclipse this might suit your purposes:

The eclipse plug-in ecosystem is vast, so there's bound to be something that will
meet your needs. Good luck, and sorry I can't be more definitively helpful.
