History
In 2001, IBM donated the Eclipse Platform into Open Source to enable community-driven development of a Java workbench and tools. Eclipse was based on standards like J2EE and was designed with a plug-in based framework so that vendors could easily extend the features of the workbench.
Also in 2001, IBM replaced the VisualAge for Java and WebSphere Studio products with WebSphere Studio Application Developer (WSAD), version 4.0. WSAD extended the Eclipse platform and included tools to develop Web services and XML applications, and for performance profiling.
In 2002, IBM released version 5.0 of WSAD adding a Java Visual Editor, an XSL debugger, and test and analysis tools. Applications could be deployed to WebSphere Application Server version 5.0. New supported programming standards included J2EE 1.3.
In 2003, IBM completed the purchase of Rational Software and a year later, replaced WSAD with Rational Application Developer version 6.0. This release supported WebSphere Application Server version 6.0 and updated programming standards such as J2EE 1.4. Also included were tools for visual portlet and portal development.
In 2006, IBM donated the Web Tools Platform (WTP) to Eclipse. WTP included tools for developing Web and Java EE applications. That year also saw the release of Rational Application Developer version 7.0, with new features supporting Java Server Faces, and tools for XSD and WSDL visualization and transforms. In this release, Rational Application Developer could be installed in a single workbench with other Rational tools.
In 2008, IBM released Rational Application Developer version 7.5. This release supported WebSphere Application Server version 7.0 as well as the new Java EE 5 programming standard. This release included tools for Service Component Architecture (SCA), a component-based programming model, and tools for communication enabled applications.
In 2010, IBM released Rational Application Developer version 8.0. This release supported WebSphere Application Server version 8.0 as well as the new Java EE 6 programming standard. This release included tools supporting the OSGi applications framework and cloud computing. The cloud computing support included the ability to instantiate and manage virtual machines running application servers and also inclusion of virtual machine appliances for Rational Application Developer in the IBM SmartCloud Enterprise image catalog.
The latest version of Rational Application Developer is Version 8.5, which was released in June 2012.
