Michael,
I have made a change in ejbjar so that a NoClassDefFound error is not
fatal. The code was catching ClassNotFoundExceptions so this is not a major
change. It basically means that while the loader did find your class, it
could not find another class upon which it depended. There can be a few
reasons for that, especially due to interaction between the classpaths of
the ejbjar class loader and the system classloader.
Before you pick up this change, can you please run ant -debug and send me
the output. Probably easier to read if you zip it and send it to me
directly. In debug mode, the AntClassLoader will each class load attempt
and which loader will be responsible.
Jeff, the same would probably apply to you.
Once you do pick up this change, you will most likely get a warning about
being unable to load a superclass or superinterface. If you let me know
about those too, it would be good.
Conor
