Web Services Addressing 1.0 provides a mechanism to developers on how  
to address objects for Web services applications. It extends the  
capabilities of Web services by enabling asynchronous message  
exchanges, and allowing more than two services to interact.

In short, think of the functionalities provided by cookies, and  
improve upon those. Think of single sign-in. These are scenarios  
where WS-Addressing is designed to work.


Web Services Addressing 1.0 provides a transport-neutral mechanism  
for addressing objects in Web services applications built on top of  
URIs. This new method is called an endpoint reference, or EPR. EPRs  
are designed to solve the issues posed by specific scenarios:

      * Dynamic generation and customization of service endpoint  
descriptions - such as those created for a session id or customer id
      * Referencing and description of specific service instances  
that are created as the result of stateful interactions
      * Flexible and dynamic exchange of endpoint information in  
tightly coupled environments where communicating parties share a set  
of common assumptions about specific policies or protocols that are  
used during the interaction.

yes. The WS vendors have been eager to get this done, as many other  
specifications developed elsewhere depend on it.

Well, a short cut might be to use the MS testimonial - here it is:

Microsoft Corp. is pleased to see WS-Addressing 1.0 become a W3C  
Recommendation. As co-authors and implementers of the original WS-  
Addressing submission in 2004, Microsoft has long viewed having a  
standard method of addressing messages as a fundamental extension to  
SOAP. Many other specifications, such as WS-Trust, WS-  
ReliableMessaging, and WS-Coordination, leverage this facility to  
provide secure, reliable, transacted Web services that interoperate  
across platforms. Microsoft will continue its support of WS-  
Addressing by implementing the W3C Recommendation in the next  
versions of its Web services-enabled products, including the  
forthcoming Windows Communication Foundation 1.0

-- Andrew Layman, Director of Connected Systems Integration,  
Microsoft Corporation


Good luck with JavaOne.
