AJAX Toolkit Framework for Eclipse

The proposal for incubation of the AJAX Tookit Framework within Eclipse WTP can be found here. The proposal states that the

AJAX Toolkit Framework (ATF) will provide extensible frameworks and exemplary
tools for building IDEs for the many different AJAX runtime offerings (Dojo,
Zimbra, etc). These frameworks will contain features for developing, deploying,
debugging and testing AJAX applications.

The initial set of tools built on these proposal will include:

• Enhanced Javascript editing features such as Batch and runtime (as-you-type) syntax validation.
• A JavaScript debugger that will be tightly integrated with Eclipse debug UI.
• Embedded Mozilla browser.
• Embedded DOM browser.

ATF will also provide for the development and incorporation for additional AJAX development tooling. ATF will use Eclipse extensions for Web application development to make the environment "server agnostic". More information about AJAX can be found in my other blog entry "AJAX and J2EE".
They are looking for contributors as of this date.
