I GOT IT!!!

Thanks for all of you that gave me pointers.

The included prj.el will set all the arguments necessary to use JDE with
ANT.
There are two variables that control whether you want to use ANT:

 jde-build-use-ant ;; You should set this in your .emacs file
                   ;; This allows some people using ANT and others not
                   ;; If you set it in prj.el, everyone will build with it.

 jde-ant-project-file ;; the name of the buildfile relative to the prj.el
file.
                      ;; defaults to "build.xml" but if different should be
set 
                      ;; on prj.el file.


It works quite well.
If you want to allow additional parameters to ANT, then make
jde-read-make-args non-nil.

Jose Alberto
PS: Maybe someone can make an actual ant-mode out of this. That we can give
with the distribution.
