Thank you vickyk!
When I invoke this function in ManagedConnection:
void connectionClosedEvent()
| {
| Iterator it = connectionListeners.iterator();
| while (it.hasNext())
| {
| ConnectionEventListener listener =
| (ConnectionEventListener) it.next();
| ConnectionEvent temp = new ConnectionEvent(this, ConnectionEvent.CONNECTION_CLOSED);
| listener.connectionClosed(temp);
| }
| }
when it arrives at lstener.connectionClosed(temp), the following error appears:
20:11:48,484 INFO [NoTxConnectionManager] Throwable from unregisterConnection
| java.lang.IllegalStateException: Trying to return an unknown connection2! null
| at org.jboss.resource.connectionmanager.CachedConnectionManager.unregisterConnection(CachedConnectionManager.java:342)

| .................
| 20:11:48,531 INFO [NoTxConnectionManager] Unregistered handle that was not registered! null for managedConnection: com.jca.FileManagedConnection at 5f62a9
Then I go on it invoke connectionClosedEvent() again!! I really don't know why. This time the console prints the following Info:
| 20:19:02,484 INFO [CachedConnectionManager] Closing a connection for you. Please close them yourself: com.jca.FileConnectionImpl at 473996
