public class ContainerManagedServiceBean
extends ContainerManagedServiceBeanBase
implements javax.ejb.SessionSynchronization

BaseClass for deploying an appmodule service methods as session bean with container managed transaction. This class implements the javax.ejb.SessionSynchronization and provides a TransactionHandlerFactory implemnatation for associating the bean transaction with the bc4j transaction.
