Callisto, to be officially known as Eclipse Platform 3.2, will feature a follow-up release of Web Tools Platform that features J2EE 1.5 tooling, including support for Java annotations, which allows for embedding of comments directly into code.

Other Eclipse offerings to be featured in Callisto include tools from the Data Tools Platform, Test & Performance Tools Platform, and Business Intelligence and Reporting Tools projects. The Eclipse IDE will be included as well.

The consolidated release of Eclipse technology is driven by efficiency. Users get all the technologies at once, and they will work together. "It will end the discovery problem" pertaining to Eclipse technologies by providing multiple offerings in one download, Wagner said. Commercial companies will be able to build products on top of Callisto.

Callisto is a natural evolution of the Eclipse platform, Willett said. "They're getting a lot more granular in terms of what Eclipse covers," he said.
