OASIS Members Demonstrate Interoperability for WS-Reliability Specification

Fujitsu, Hitachi, NEC and Oracle Showcase Reliable Web Services

OASIS Members Demonstrate Successful Interoperability of Reliable Messaging for Web Services at Technical Committee Meeting

Redwood Shores, CA, USA. September 04, 2003.

Fujitsu Limited, Hitachi, Ltd., NEC Corp. and Oracle Corp. today announced that they have successfully demonstrated interoperability between four independent implementations of reliable Web services based on the Web Services-Reliability (WS-Reliability) specification, which the companies jointly submitted to the Organization for the Advancement of Structured Information Standards (OASIS) in January. The WS-Reliability specification defines an open reliable messaging infrastructure that enables companies to conduct reliable business-to-business trading or collaboration using Web services. This demonstration is the first deliverable of an ongoing Proof-of-Concept activity for the Web Services-Reliability specification. The OASIS Web Services Reliable Messaging (WS-RM) Technical Committee members plan to update their implementations to accommodate the upcoming release of the next version of the specification, already under development by the committee.

The interoperability demonstration will be conducted today during the latest WS-RM Technical Committee meeting in Bedford, Massachusetts. The WS-Reliability specification enabled the four Web service applications used in the Proof-of-Concept demonstration to reliably exchange messages over an unreliable network test bed that simulates message loss, duplication and delays. The network test bed will be used by the group for future WS-Reliability interoperability tests. Additional supporters of WS-Reliability are expected to participate in future Proof-of-Concept demonstrations.

The demonstration highlights two functions of the WS-Reliability specification. The first one is "Guaranteed Delivery" in which the sender will automatically resend the same message if no positive acknowledgement was received, and the other is "Duplicate Elimination" in which the receiving application eliminates duplicates of the same message. These two functions greatly improve the reliability and efficiency of business applications, by preventing message loss and duplication. This will allow, for example, buyers to ensure that Purchase Order messages are successfully delivered to their suppliers, and prevent suppliers from receiving duplicate orders due to network routing problems.

In addition to guaranteed delivery and duplicate elimination, the OASIS WS-Reliability specification also addresses message delivery management, including message persistence, ordered delivery, and delivery status notifications for sending and receiving applications.
