All Implemented Interfaces:

EventListener, javax.management.MBeanRegistration, javax.management.NotificationBroadcaster, javax.management.NotificationEmitter, CachedConnectionManagerMBean, org.jboss.system.Service, org.jboss.system.ServiceMBean, org.jboss.tm.usertx.client.ServerVMClientUserTransaction.UserTransactionStartedListener

public class CachedConnectionManager
extends org.jboss.system.ServiceMBeanSupport
implements org.jboss.tm.usertx.client.ServerVMClientUserTransaction.UserTransactionStartedListener, CachedConnectionManagerMBean

The CachedConnectionManager mbean manages associations between meta-aware objects (those accessed through interceptor chains) and connection handles, and between user transactions and connection handles. Normally there should only be one such mbean. It is called by CachedConnectionInterceptor, UserTransaction, and all BaseConnectionManager2 instances.
