A discussion of a JBoss Messaging issue related to EJB3 MDBs (http://www.jboss.com/index.html?module=bb&op=viewtopic&t=80525) resulted in a proposed patch to DLQHandler.createSevice to log the exception that is thrown because even though it is linked to a JMSException, it never shows up anywhere in the log files. If this is agreeable, let me know and I will open a JIRA issue and submit the patch.

Proposed patch, new line in red:

protected void createService() throws Exception
{
 ...
 try
 {
 ...
 }
 catch (Exception e)
 {
 if (e instanceof JMSException)
 throw e;
 else
 {
 log.error("Error creating the dlq connection", e);
 JMSException x = new JMSException("Error creating the dlq connection: " + e.getMessage());
 x.setLinkedException(e);
 throw x;
 }
 }
 ...
}
