xmlBlaster guarantees exactly one delivery. However - on certain crash situations a message may be resent (when the server got no ACK). Avoiding this needs transaction support (two phase), which is not yet implemented. Redeliverd messages are marked with the QoS tag <redeliver>12</redeliver> See http://www.xmlblaster.org/xmlBlaster/doc/requirements/engine.callback.html regards Marcel -- http://www.xmlBlaster.org
