Java Enterprise in a Nutshell, Second Edition

Name

UserException

Synopsis

This is the base class for all user exceptions that are defined in IDL and mapped to Java. It extends java.lang.Exception directly, so it represents a Java user exception that must be declared in method signatures and caught in application code that calls these methods. Unlike the SystemException, the UserException class doesn’t declare any data members for describing the exception to the caller. Subclasses must do this to suit the type of exception that they represent. It does, however, inherit the message property from Throwable, which can be used to store a descriptive message on the exception to describe the reason.

                  
public abstract class UserException extends Exception implements org.omg.CORBA.portable.IDLEntity {
