The products and their pages are:
- WebSphere Process Server (WPS)
- WebSphere Enterprise Service Bus (WESB)
- WebSphere Integration Developer (WID)
WID is the Eclipse-based IDE for WPS and WESB, the successor to WebSphere Studio Application Developer Integration Edition (WSAD-IE) (analogous to RAD's relationship to WAS). The WESB materials include a WESB FAQ.
There's also a new article on WPS: "WebSphere Process Server: IBM's New Foundation for SOA." The lead author, Wolfgang Kulhanek, has been featured in a Meet the Experts: Wolfgang Kulhanek on WebSphere Business Integration.
Of course, all of this ties into the recent Flurry of IBM SOA Announcements and IBM's SOA Materials.
