Hi, Raymond:
Thanks for pointing out my problem. I read the part you specified in JAXWS
specification and understand that RemoteException and RuntimeException are
not suitable for service specific exceptions.
But if I want to provide the following interface with RMI service binding:
public interface OrderManagement {
public void placeProcessOrder(String userID) throws
UserPriviledgeNotEnoughException;
}
How can I achieve the goal if I doesn't specify
UserPriviledgeNotEnoughException as a RemoteException? RMI client runtime
will complain a non-remotable exception. Could you give me some indication
or best practices to work around this in Tuscany way?
Best Regards,
Yang Sun
