We are porting some of our ws to jbossws. We used jsr-181 and we ported with success all basic functionalities. To improve interoperability we are interested in implementing exception handling passing custom Exceptions as Soap faults.
What basically we did is to decorate some methods throwing custom defined exceptions with jsr-181 annotations. All exceptions extend java.lang.Exception and should be serializable because they are implemented as standard javabeans.
We are experiencing deploy problems getting this exception:
