In 2006, Apple announced the deprecation of Mac OS X's Cocoa-Java bridge with the release of Xcode 2.4 at the August 2006 Worldwide Developers Conference, and with it all dependent features, including the entire suite of WebObjects developer applications: EOModeler, EOModeler Plugin, WebObjects Builder, WebServices Assistant, RuleEditor and WOALauncher. Apple had decided to concentrate its engineering resources on the runtime engine of WebObjects, leaving the future responsibility for developer applications with the open-source community. The main open-source alternative — the Eclipse IDE with the WOLips suite of plugins — had matured to such an extent that its capabilities had, in many areas, surpassed those of Apple's own tools, which had not seen significant updates for a number of years.
