Update an existing JAR

[Andy Miller <am...@emerging.com>]

In Ant, is there anyway to append files to an existing JAR instead of having
to create it from scratch everytime?  

I would like to have a single JAR that contains some EJBs plus some other
misc. classes that do not specifically pertain to the EJB.  I have Ant
building the EJB jar just fine, but can't find a way to add other classes to
it.

Any ideas would be appreciated.

Thanks,
