    Exposing Application Module as Webservice - Query

    S. Saravanan-Oracle
      Hi,
           I have a few queries regarding ADF Business Components. It will be great if you guys answer these queries:

      1. Application Module can be exposed as web service. In this scenario, does ADF support clustering?
      2. If AM is exposed as WS, what is the implication in terms of performance and availability?
      3. I could not find information related to clustering, performance and availability of WS in ADF developer guide. So, please provide any similar implementations, support statements, articles, blogs, etc for the above two queries.


      Thanks & Regards,
      Saravanan.

          Saravanan, there is a powerful, new web services feature in ADF BC in the 11g release called "Service Interface". If you use the Technology Preview 4 release from OTN, you can follow
          along with this Oracle Magazine article to learn more about the
          feature: [Services
          with a Smile|http://www.oracle.com/technology/oramag/oracle/08-jan/o18frame.html]

          Unfortunately, since the feature depends on some SOA infrastructure
          that was not ready in time on WebLogic for the first production
          JDeveloper 11g release (due out on OTN very, very soon), the Service
          Interface feature had to be removed along with the Business Events feature
          from the initial JDev/ADF 11g production release. It is planned to be
          re-introduced in the JDev/ADF release that will ship with the full
          Oracle Fusion Middleware 11g production release in the first half of
          calendar 2009.

          So, in the initial JDeveloper 11g production release the only kind of
          web services that can use ADFBC components would be ones you
          hand-create. As stateless components, they should work fine in a
          clustered environment (both now and when the "Service Interface"
          feature goes production along with the complete FMW 11g suite.
