Examples of java.rmi.ServerException

java.rmi.ServerException
A ServerException is thrown as a result of a remote method invocation when a RemoteException is thrown while processing the invocation on the server, either while unmarshalling the arguments or executing the remote method itself. A ServerException instance contains the original RemoteException that occurred as its cause. @version 1.16, 11/17/05 @author Ann Wollrath @since JDK1.1
