Hi
We encountered with the same problem and found that in case of
java.lang.Error was thrown on the server side axis just ignores the cause
and answers to client with just InvocationTargetException without the cause.
It is inconsistency in axis because in case of java.lang.Exception client
aware to the cause. The example of java.lang.Error is OutOfMemoryErrror and
StackOverflowError. I don't see any reason not to transfer the cause to the
client side.
The question to axis guys: are there any plans to fix the error notification

tnx
