org.jboss.resource.connectionmanager.BaseConnectionManager2
The BaseConnectionManager2 is an abstract base class for JBoss ConnectionManager implementations. It includes functionality to obtain managed connections from a ManagedConnectionPool mbean, find the Subject from a SubjectSecurityDomain, and interact with the CachedConnectionManager for connections held over transaction and method boundaries. Important mbean references are to a ManagedConnectionPool supplier (typically a JBossManagedConnectionPool), and a RARDeployment representing the ManagedConnectionFactory. @author David Jencks @author Erwin Guib @author Adrian Brock @author Weston Price @author Anil.Saldhana@redhat.com @version $Revision: 103541 $
