AccessLocalException, TransactionRequiredLocalException, NoSuchEntityException, NoSuchObjectLocalException, NoSuchEJBException, TransactionRolledbackLocalException, EJBAccessException, EJBTransactionRolledbackException, EJBTransactionRequiredException, ConcurrentAccessException

The EJBException exception is thrown by an enterprise Bean instance to its container to report that the invoked business method or callback method could not be completed because of an unexpected error (e.g. the instance failed to open a database connection).

Constructor:
public EJBException() { } Constructs an EJBException with no detail message.
public EJBException(String message) { super(message); } Constructs an EJBException with the specified detailed message.
public EJBException(Exception ex) { super(); causeException = ex; } Constructs an EJBException that embeds the originally thrown exception.
public EJBException(String message, Exception ex) { super(message); causeException = ex; } Constructs an EJBException that embeds the originally thrown exception with the specified detail message.

Constructor:

 public EJBException() {

}

Constructs an EJBException with no detail message.

 public EJBException(String message) {
        super(message);
}

Constructs an EJBException with the specified detailed message.

 public EJBException(Exception ex) {
        super();
	causeException = ex;
}

Constructs an EJBException that embeds the originally thrown exception.

 public EJBException(String message,
    Exception ex) {
        super(message);
	causeException = ex;
}

Constructs an EJBException that embeds the originally thrown exception with the specified detail message.
