Apache Axis 2 Project Plan

Requirements and initial architecture was discussed between the 21st-24th of August 2004 in Colombo. It was decided that we prototype some of the identified components for a period of three months before a final plan for Axis 2.0 is prepared.

Prototyping

The following components are being prototyped:

• OM
• Engine
• Deployment
• Data Binding
• WSDL
• Client API

High Level Plan

1. Start Date: 25th August 2004
2. Tentative End Date : 10th December 2004
3. Integration and working prototype to be available on or before the 31st of December 2004

Milestone Release Plan for Axis2 01/M1

• Release Plan http://wiki.apache.org/ws/FrontPage/Axis2/Release01M1

• TO DO's http://wiki.apache.org/ws/FrontPage/Axis2/ToDo01M1

Sanjiva

• (1) OM interfaces supporting the base SOAP Infoset (i.e., without MTOM) (2) OM implementation (3) Engine supporting
  • - "phased handlers" architecture complete - burnt-in concepts of WS-Addressing, suitably abstracted to make sure system can run with or without WS-Addressing headers - ability to deploy modules consisting of one or more handlers slotting into various phases - servlet HTTP transport

    - native HTTP transport (use code from SimpleAxisServer?) - support for ReplyTo style redirection even for HTTP cases - hot deployment of services - no service isolation - no data binding

  (4) Programming model for service implementors
  • - Only Java code supported - For WSDL 1.1 request-response style operations:
    • - Blocking:
      • Option 1: OM doFoo (OM)
        • (Basically take in an OM and produce an OM. This is good
          • for anyone who just wants the payload to play with and wishes to produce a payload to ship out.)
        Option 2: MC doFoo (MC)
        • (Basically take in the whole message context and produce
          • an MC .. which is the programming model for a handler too I guess!)
      - Non-blocking:
      • void startDoFoo (MC)
        • (App gets the message and when its ready to send the response (using the same thread or another thread or whatever), uses the client API to send it. Note: Method may return without having completed the response writing.
    - For WSDL 1.1 input-only style operations:
    • - void doFoo (OM) - void doFoo (MC) (App can consume just the payload or the full MC.)
  (5) Programming model for clients
  • - Blocking and non-blocking programming models (sync/async) - Details TBD
  (6) Deployment descriptor for services: service.xml (as discussed in Wiki) (7) Deployment descriptor for engine: engine.xml (as discussed in Wiki (?)) (8) Deployment descriptor for modules: module.xml (as discussed in Wiki) (9) Packaging/directory hierarchy for engine: as discussed in Wiki (10) Design docs, architecture docs, user guide update sufficiently to allow people to play with the M1 release.
