 			This section provides a functional overview of the Java EE subproject in WTP.

 			<h4>Java EE Project Creation</h4>
 			Project creation wizards, operations and the data models that drive the
 			operations are used to create Java EE projects. The project creation wizards
 			can be launched using the File &gt; New &gt; Project menu action. The Java EE
 			projects include Enterprise Application, Web, Application Client,
 			Enterprise Java Bean and Connector projects. These Java EE projects can be
 			created for Java EE specification level 1.2, 1.3, 1.4 Java EE 5 and 6 and targeting to a
 			Java EE specification compatible application server. A Java EE runtime target
 			(target server) should be predefined for project creation. The runtime
 			targets are a mechanism to set the JRE and Server classpath on a Java EE
 			project for compile time. The Java EE module projects Web, Application
 			Client, Enterprise JavaBean and Connector projects can be created as
 			standalone or can be nested under a new or existing Enterprise
 			Application project. The api that are available to create the Java EE
 			projects are discussed in the Api Overview section.

 			<h4>Java EE Archive Import</h4>
 			Import wizards and operations and data models that drive the operations
 			are used to import Java EE archives (ear, war,jar.rar) into the workbench.
 			The import wizards can launched using the File &gt; Import menu action. The
 			Java EE archives can be imported into new or existing Java EE projects. For new
 			projects, a runtime target (target server) must be predefined. When
 			importing into an existing project, the user has the option to overwrite
 			the contents of the project with that of the archive and also delete the
 			project and create and new one. The Enterprise Application wizard has
 			more options to import modules nested in a EAR file. The api that are
 			available to import Java EE archives are discussed in the Api Overview
 			section.

 			<h4>Java EE Module Export</h4>
 			Export wizards , operations and data models that drive the operations are
 			used to export Java EE projects into deployable archives (ear, war, jar,
 			rar). The export wizards can be launched using File &gt; Export menu action.
 			The export wizards have the option to include Java source also using
 			export of the Java EE projects. The export of an Enterprise Application
 			project also exports all the associated modules into the ear that can be
 			deployed to a Java EE application server.

 			<h4>Java EE Project Explorer contributions</h4>
 			The Project Explorer provides a single, consistent view that allows users
 			to explore rich levels of content. Physical and logical content is
 			integrated seamlessly to allow users to browse Eclipse resources, Java
 			packages and classes, navigable models of configuration information,
 			Databases, Database Servers and Web Services among other enhanced
 			content. Java EE deployment descriptor models are contributed for fast
 			visual inspection of a modules content, and several menu actions are available
 			for related activities (Run on server, open editor etc...)

 			<h4>Java EE Server Deployment</h4>
 			Built on WTP's' common project's "Deployment Assembly" framework, Each Java EE
 			project has the flexibility to assemble source from various locations, and map
 			folders, libraries, and classpath entries into a given deployment directive

 			<h4>Java EE Validation</h4>
 			Underlying in memory models are used to validate relevant artifacts, the various
 			validator's are built on WTP's validation framework. Utilizing JDT(Java) api's and
 			deployment descriptor model's - Specification rules are checked to catch problems
 			at development time, and to ensure deployment to various runtimes goes smoothly.
