Oracle and MS lead appserver platforms
The serverside is reporting on a Forrester report: The Forrester Wave: Application Server Platforms Q1 2005. Basically Forrester is saying that both MS and Oracle offer the most complete solution with their application servers. Not many people seems to agree with this on the Serverside, most people think either Oracle or Microsoft payed for this report.
That may or may not be true, but fact is that Oracle is working hard on offering a good and complete application server. Some examples: BPEL support in the application server, and Oracle is already offering a developer preview of EJB 3.0. They’re also working pretty hard on their IDE: see for example the JSF support in JDeveloper.
