2. Re: JBoss error:Trying to return an unknown connection2!....
liujw2001 Oct 18, 2007 8:27 AM (in response to liujw2001)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) at org.jboss.resource.connectionmanager.NoTxConnectionManager$NoTxConnectionEventListener.connectionClosed(NoTxConnectionManager.java:88) at com.jca.FileManagedConnection.connectionClosedEvent(FileManagedConnection.java:178) at com.jca.FileConnectionImpl.close(FileConnectionImpl.java:20) at com.ejb.FileEJB.getTextFile(FileEJB.java:39) ................. 20:11:48,531 INFO [NoTxConnectionManager] Unregistered handle that was not registered! null for managedConnection: com.jca.FileManagedConnection@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@473996 java.lang.Throwable: STACKTRACE at

Where is this code from ?
Looks like you have written your own RAR file and it causes issues .
