Aaron,
Thanks for the reply, this problem's driving me nuts. My finder DOES declare
FinderException and RemoteException
(and thats all). Its a container managed Bean, but it is a custom finder.
Yeah, I'd never heard of UndeclaredThrowableException either... its new with Java 1.3,
which is new to me since
I'm on a linux box. It gets thrown when a the calling of a Method object's invoke
method results in an exception
being thrown that is not listed in that Method's throw clause. In this case, the
nested exception is a
java.io.NotSerializableException, which indeed is not declared in my finder method's
throw clause. Thats also why
I think it might be a serialization problem.
In the stacktrace I included with my first post, the NotSerializableException had
org.jboss.tm.TxManager in its
message portion... could this mean that somehow something is trying to serialize the
transaction manager?
