More on the subject of reliable messaging:

BEA recently released 3 "WS-X" specifications, one of which
(WS-Acknowledgement) addresses reliable messaging:

   WS-Acknowledgement
   WS-Callback
   WS-MessageData

More details:
  
* WS-Acknowledgement: Designed to support reliable message exchange
between services by providing for at-least-once and exactly-once SOAP
message transfer guarantees;

* WS-Callback: Used to dynamically specify where to send asynchronous
responses to a SOAP request;

* WS-MessageData: Enables the re-use of meta-data about a message across
SOAP extensions;

Now there are 3 reliable messaging specifications "out there":

(1)WS-Reliability (SUN and others, being developed under OASIS 	WSRM TC)
(2)WS-ReliableMessaging (part of GXA)
(2)WS-Acknowledgement (BEA)
 	
From (at least) a very high-level standpoint, one may observe that all 3
of these specifications are in fact very similar.
