Major Vendors Showcase Reliable
Web Services
Fujitsu Limited, Hitachi Ltd, NEC Corp and Oracle Corp 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, Mass. 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.
