ServiceMix can handle failure and recovery of messages, you just need
configure the endpoints to handle this using message persistence and
transactions. In your component flow noted above, this means that you
will need to do the following:

1) Make sure that the message producer (i.e., your client) who is
sending messages to the JMS destination does so using
javax.jms.DeliveryMode.PERSISTENT
2) Use the jms:consumer instead of the jms:endpoint for your JMS
consumer BC (see
http://servicemix.apache.org/servicemix-jms-new-endpoints.html for
more information) and set transacted="jms" in the xbean.xml
3) Make sure to set the
javax.jbi.messaging.MessageExchange.JTA_TRANSACTION_PROPERTY_NAME
property from within your servicemix-bean SUs' bean class (this makes
the message exchange persistent)
