  • Overview
    • The AJAX Toolkit Framework (ATF) is an Integrated Development Environment (IDE) for AJAX developers and an extensible framework for adding AJAX runtimes in to the IDE. It is an open-source project in incubation phase on Eclipse.
    • Provides
      • Tools to develop any DHTML/AJAX application
