Great idea! I haven't tried this (the code below) yet, but it seems like a
good approach -- it's Emacs, so let the user customize how to invoke Ant!

Subject: Re: jde-ant
Hello,
I have completed, the first stage, of the modifications to jde-ant.el
which allows a user to select the invocation style, either script or
via Java. I have added appropriate comments to the jde-ant.el file to
indicate the changes. I will repeat here:
added 3 custom variables
jde-ant-class
indicates which java class to invoke
default value is org.apache.tools.ant.Main
jde-ant-classpath
List of jar files needed to run ant.
This needs to be set to include the 3 ant jar files
and the tools.jar from Sun.
I have chosen to use this instead of using the global
classpath as the jar files used to invoke ant is not
necessarily needed to compile the classes. I think, IMHO,
this makes it cleaner.
jde-ant-invocation-style
Used to determine how to invoke jde-ant, the default how
Jason would like to see it.
Added 1 defun
jde-ant-build-classpath
This defun creates the classpath from the list of jars in
jde-ant-classpath.
To Do:
Add one more customer var to indicate the home directory of Ant.
Thereby, automatically creating the required classpath to include
the 3 ant jar files and the tools.jar from Sun. This allows the
user to include the additional jar files they need to run ant
and not worry about the required jars.
If I have made a error please let me know.

P.S. If you can come up with better wording for the
jde-ant-invocation-style I would be very much appreciated.
