No pong received warning

[gmeroz]

we get the following warning over and over when using MDB JBossAS4.0.5GA. Is there any way to solve it?

10:35:18,032 WARN [Connection] Connection failure, use javax.jms.Connection.setExceptionListener() to handle this error and reconnect

Hi!

FAQ is found under:

http://wiki.jboss.org/wiki/Wiki.jsp?page=IGetIOExceptionPingTimeoutHowDoIFixIt

We have similar Exceptions here with JBoss 4.2.1 GA. At the moment our oracle database isn't available for about an hour each night. We have no client using JMS. All happens on the server side.

The following exceptions can be found in the jboss.log:

01:52:43,313 WARN [Connection] Connection failure, use javax.jms.Connection.setExceptionListener() to handle this error and reconnect

Even though the database is back online for a couple of hours the exceptions only disappear when jboss is restarted.

The FAQ only says :

I'm inside the application server, how do I install the exception listener?

* You don't need to for an MDB, JBoss does it for you.

This doesn't seem to be true in every case.

Any hints?

Thanks in advance

It says more than that. It doesn't log the shown warning for MDBs or
the jms resource adapter, you get a different warning from their installed
exception listeners.

If it says there is no ExceptionListener installed then that is the case.

There is no WARNing if there is an exception listener installed (unless
the exception listener is recursing).

 synchronized (elLock)
 {
 ExceptionListener el = exceptionListener;
 if (el != null && elThread == null)
 {
 try
 {
 Runnable run = new ExceptionListenerRunnable(el, excep);
 elThread = new Thread(getThreadGroup(), run, "ExceptionListener " + this);
 elThread.setDaemon(false);
 elThread.start();
 }
 catch (Throwable t1)
 {
 log.warn("Connection failure: ", excep);
 log.warn("Unable to start exception listener thread: ", t1);
 }
 }
 else if (elThread != null)
 log.warn("Connection failure, already in the exception listener", excep);
 else
 log.warn("Connection failure, use javax.jms.Connection.setExceptionListener() to handle this error and reconnect", excep);
 }

Any hints?

Thanks in advance
