The Web Tooling Platform (WTP) Project is made up of two subprojects, Web Standard Tools (WST) and J2EE Standard Tools (JST).
The Web Standard Tools subproject aims to provide common infrastructure available to any Eclipse-based development environment targeting Web-enabled applications. Within scope will be tools for the development of three-tier (presentation, business and data logic) and server publication of corresponding system artifacts. Outside scope will be language or web framework specific technology, which will be left to other subprojects like the J2EE Web Tools subproject.
Tools provided will include editors, validators and document generators for artifacts developed in a wide range of standard languages (for example, HTML/xHMTL, Web services, XQueries, SQL, etc.) Supporting infrastructure will likely comprise a specialized workbench supporting actions such as publish, run, start and stop of Web application code across target server environments.
The initial scope of the J2EE Standard Tools subproject will be to provide a to provide common infrastructure for developing applications based on J2EE 1.4 targeting J2EE-compliant application servers, as well as a more generic J2EE tooling infrastructure for other Eclipse-based development products.
Tools provided will include a workbench for developing, deploying, testing and debugging J2EE applications on JCP-compliant server environments, as well as an exemplary implementation of a plug-in for at least one JSR-88 compliant J2EE Server. Included will be a range of tools simplifying development with J2EE APIs including EJB, Servlet, JSP, JCA, JDBC, JTA, JMS, JMX, JNDI, and Web Services. This infrastructure will be architected for extensibility for higher-level development constructs providing architectural separations of concern and technical abstraction above the level of the J2EE specifications
The integrated workbench to be delivered would support use cases such as " - Develop a JSP page, Enhance the "PetStore" blue-print application, Expose a Session Bean as a Web Service".
