1. System Exception : is an unchecked exception produced from java.lang.RuntimeException. An EJBException is an unchecked exception, which is started from java.lang.RuntimeException.
2. Application Exception : is generic to an application and thrown because of violation of business rules. An Application Exception is a checked exception that is either described by the bean developer and does not import java.rmi.RemoteException.
