public class OpenEJBException
The OpenEJBException is the standard exception thrown by all methods in all
type in the Container Provider Interface (CPI). The OpenEJBException has 3
subtypes each serving a different purpose. The Container will always thrown
one of these subtype and should never the OpenEJBException itself.
This type is thrown when a normal EnterpriseBean exception is thrown.
The ApplicationException's nested Exception will be either an EJB
ApplicationException (a custom exception defined by the bean developer)
or a RemoteException. The org.openejb.ApplicationException must be
caught and its nested exception rethrown by the bean proxy to the client.
The org.apache.openejb.ApplicationException is non-system exception; it
does NOT indicate a problem with the contaienr itself.
This type is thrown when the EnterpriseBean throws a RuntimeException or
system exception that results in the eviction of the bean instance. The
InvalidateReferenceException's nested exception will be a RemoteException
or a RuntimeException, which must be converted to a RemoteException if
applicable for the given beany proxy type. The Application Server must
catch the InvalidateReferenceException and its nested exception rethrown
by the bean proxy (if the nested exception is a RuntimeException it must
first be converted to a RemoteException if the bean proxy is a
java.rmi.Remote proxy). After the exception is re-thrown by the bean
proxy, the bean proxy must be invalidated so that all subsequent
invocations by the client on that bean proxy throw a RemoteException. The
proxy is made invalid. InvalidateReferenceException is non-system
exception; it does NOT indicate a problem with the container itself.
This type is thrown when the container has encountered an unresolvable
system exception that make this Container unable to process requests. A
breakdown in communication with one of the primary services or a
RuntimeException thrown within the container (not by a bean) is are good
examples. The org.openejb.SystemException represents a serious problem
with the Container. The Container should be shut down and not used for
any more processing.
