Guidelines for packaging java programs?

[Bruno Wolff III]

Is there a good place to read up on how java programs (this is related to
trying to package Colossus) should be installed on Fedora? I am particularly
looking for guidelines on where to install the various peices. Other info
for someone that doesn't do java coding would be useful. The project provides
a build.xml file suitable for ant and that's what I was plannig to use
for the build process unless there is some reason I shouldn't.
