2

Current Implementation

WS Addressing: March 2004 version WSRF: June 2004 working draft WSN: June 2004 working draft SOAP 1.1 Apache Axis

Trunk: 1.5 with patches 4.0.x : 1.2 with patches

3

Specification Upgrade

Specifications: WSRF 1.2 WSN 1.3 WS Addressing 1.0

Implications No loss of functionality Some optional additional functionality Wire incompatible with older version Some OGF profiles use the final version Interoperate with other implementations

4

Support final specifications only

In place replacement Replace

Operation providers Core API Handlers that parse WS Addressing headers

5

Implications

New clients cannot interoperate with old servers and vice versa.

EPRs will be different Service developer will need to update all

WSDLs to use new specifications Minor core API change

EPR creation and processing Notification processing

6

Support both sets of specification

Container can host services that use either draft or final specifications

Treat each set of specification as operational universe

New set of operation providers and core API for final draft processing

Additional handler to parse WS Addressing final version

7

Implications

Existing client/server interaction will not change

Services that need to exist in multiple universe need Multiple WSDLs and deployment descriptors Can share application logic

Service developer must choose appropriate WSDL Operation provider Core API for specification dependent code

Questions

Do you need final versions of WSRF/WSN for your project

Do you interoperate with other WSRF/WSN implementations

Do you need to host services with draft and final versions of the specification in same container
