Subject Re: Killing activemq with connected JMS listener
Date Thu, 19 Mar 2009 09:52:47 GMT

Well I'm not agree with you. As specified by the JMS specification the
Connection object supports an optional ExceptionListener. ExceptionListener
are the best way to treat the disconnection exception or other exception BUT
without ExceptionListener you should get a disconnection exception in the
JMS listener anyway. For me the fact JMS listener do not receive any
disconnection exception without an ExceptionListener seems to be a bug from
activemq... I'll implement the ExceptionListener to check the behavior of
ActiveMQ and I keep you in touch.

Thanks for all.
