WS-Reliability was published in January 2003 by Hitachi,
Oracle, Sonic, and Sun Microsystems, and then submitted to the OASIS Web Services
Reliable Messaging Technical Committee.
The Web Services Reliable Messaging (WSRM) protocol is based on the WS-Reliable
messaging specification and was published in March 2003 by software majors
including BEA, IBM, Microsoft, and Tibco. WSRM also works similar to web services
reliability. Instead of a group, the WSRM has the notion of a sequence to ensure
message reliability concerns.
Depending upon the criticality of the business applications, varying orders of
reliability might be required and WSRM-based products will support this. However,
both the WSRM specifications are silent on many of the aspects. A few of these are
listed as follows:
Undeliverable messages??”No definition of dead letter queue.
Message priority.
Message persistence.
The above aspects are out of the scope of the WSRM specifications, even though
the implementations of reliable messaging needs to address all or any of them
depending upon the order of reliability required.
