Hey EJ,

It is nice to hear from you!  I see and read your posts on the list somet=
imes.

>[...] you can exclude ejbs like this:

>       <not>

The only hesitation I have with that is that it must be evaluating the co=
ntents of the jar files to evaluate that <not>, which must be more expens=
ive than just including/excluding based on file name. But if I needed the=
 greater naming flexibility, that would be a great way to support it.

> Why didn't you just write your own task for this Scott?

Ha, ha good question.  I stay away from writing custom tasks until things=
 have stabilized to the extent that it's worth the effort.  It's less and=
 less often that I find something I can't do with the existing tasks.  Us=
ing Ant 1.6, ant-contrib and the <script> task has really extended what I=
 used to be able to do with plain old Ant.

In this case, both WebSphere and WebLogic.  We're keeping a pretty strict=
 separation between classes that should be in the web app classloader and=
 those that should be in the EJB classloader, as one way to enforce depen=
dency direction for EJB-level classes (which should never know or care ab=
out the web app classes).

Best,
