Class Summary

AbstractInstanceLifecycleListener	Abstract implementation of all InstanceLifecycleListener interfaces which delegates events to a single method.
AbstractRemoteCommitProvider	Abstract implementation of RemoteCommitProvider.
AbstractTransactionListener	Abstract implementation of the TransactionListener interface that provides no-op implementations of all methods.
ExceptionOrphanedKeyAction	Throw a javax.jdo.ObjectNotFoundException when an orphaned key is discovered.
InstanceLifecycleEvent	Lifecycle event on a persistent instance.
JMSRemoteCommitProvider	JMS-based implementation of RemoteCommitProvider that listens for object modifications and propagates those changes to other RemoteCommitProviders over a JMS topic.
