A reader asks:
I was wondering if Tuscany is part of the implmentation of the SCA features in websphere process server 6.1. And if so, whicht version of the spec (1.0?) and tuscany implementation (1.01?) will be used.
I've talked about the WebSphere Process Server 6.1 Announcement (WPS), planned to be available about a month from now. I've also talked about Apache Tuscany, a project to develop an open source implementation of the service component architecture (SCA) and service data objects (SDO) specifications developed by the Open Service Oriented Architecture (OSOA) and being ratified by OASIS. I've also talked about Overview of SOA Feature Pack for WAS 6.1, a presentation at WebSphere Technical Exchange a year ago that discussed IBM's plans at the time for incorporating Tuscany into WebSphere Application Server and related products (incl. WPS, which is built on WAS). This discussion of what's in WPS 6.1 also applies to WebSphere ESB 6.1 and WebSphere Integration Developer 6.1.
So where are we currently? Apache Tuscany 1.0, which implements the SCA 1.0 specs, was released two months ago. IBM WebSphere Application Server V6.1 Feature Pack for SOA is still in Beta and working to incorporate the latest version of Tuscany.
Since the SOA Feature Pack is still Beta and WPS 6.1 is final, WPS 6.1 does not incorporate the SOA Feature Pack (but does incorporate WAS 6.1). The plan is still to have a release of WPS that will incorporate the SOA Feature Pack and therefore Tuscany and therefore a standardized impl of SCA and SDO, but this is all taking longer than planned and therefore is not part of WPS 6.1. Therefore WPS 6.1 contains the same proprietary impl of SCA and SDO in WPS 6.0.x, which will make backwards compatibility and therefore migration of your existing code easier.
