First unveiled in October as part of Project Nexus, Siebel Component Assembly previously has supported deployments on Microsoft .Net and IBM WebSphere systems. IBM, BEA, and Microsoft participated in the development of Siebel Component Assembly.

Conspicuously absent from the list of supported platforms thus far is the Oracle Application Server, a fierce competitor with BEA, IBM, and Microsoft offerings. This is likely to change, however.

"We're not making any of those announcements today but that would be a safe speculation," Bernstein said. Oracle's application server is standards-based, making it a likely target for Siebel's product.

Oracle in September announced its intention to acquire Siebel Systems for $5.85 billion. The acquisition is expected to be completed in the first quarter of 2006. Siebel, Oracle, BEA, and IBM were among a list of companies last week that announced an SOA-related specification entitled Service Component Architecture (SCA).

Siebel's similarly named Siebel Component Assembly product "follows the SCA philosophy around services-wiring and Service Data Objects," Bernstein said.
