			<description>
				Several enhancements are introduced to the Servlet
				wizard. The most noticeable are:
				<ul>
					<li>
						Initialization parameters are now displayed in a
						table view. The user can easily see parameter's
						name, value and description.
					</li>
					<li>
						Servlet mappings are now validated. If a user
						enters an invalid servlet mapping, then an error
						message appears and the wizard cannot be
						finished.

			<description>
				There are now three wizards for creating web artifacts:
				<ul>
					<li>Servlets</li>
					<li>Servlet Filters</li>
					<li>Application Lifecycle Listeners</li>
				</ul>
				<br />
				They represents the web artifacts, which are based on Java classes.
				For easier access these wizards are now available in the context menu of the
				<i>Dynamic Web Project</i> as a separate action group.

		<item title="Rearrangement of the toolbar in the Java EE perspective">
			<description>
				The old toolbar section of five buttons for invoking the 
				Java EE project wizards is now replaced by two pulldown 
				buttons: 
				<ul>
					<li>
						for invoking the Java EE project wizards (Web, EJB, EAR, etc.)
					</li>
					<li>
						for invoking the Java EE artifact wizards (Servlet, Session Bean, etc.) 
					</li>

		<item title="EAR 5.0 Bundled Libraries Support">
			<description>
				In accordance with the Java EE 5 specification, a couple of
				enhancements are introduced in the EAR 5.0
				<i>Java EE Module Dependencies</i>
				property page:
				<ul>
					<li>new column with check-boxes appears in the modules table,
						allowing the user to choose if a certain bundled library should be
						packed in the EAR's library directory;</li>
					<li>
						new
						<i>Change Library Directory</i>
						button appears on the same page to allow the user to change easily
						the location of the library directory.
					</li>
				</ul>
				<br />
				<br />

				<br />
				<br />
				<br />
				Appropriate message dialogs pop up in the
				<i>Java EE Module Dependencies</i>
				property page to warn and allow the user to automatically resolve
				conflicts between EAR packing and MANIFEST.MF class path
				dependencies.

		<item title="Java EE Deployment Descriptor Nodes">
			<description>
				Deployment Descriptor nodes for Java EE 5 projects are introduced.
				This nodes are shown in the project explorer and apply for:
				<ul>
					<li>EJB 3.0 project</li>
					<li>Web 2.5 project</li>
					<li>EAR 5.0 project</li>
				</ul>
				<br />
				<br />
				<img src="javaee/ddNodes.png" alt="Java EE Deployment Descriptor Nodes" />
				<br />
				<br />
				<br />
				According to the Java EE specification artifacts can be described
				both in the deployment descriptor and with the use of java
				annotations in the source code. Current implementation will show you
				a merged view between the artifacts described with java annotations
				and those described in the deployment descriptor.
				<br />
				The result of the following annotated bean:
				<br />
				<br />
				<img src="javaee/ejbCode.png" alt="Annotated bean code" />
				<br />
				<br />
				will be:

				Merging artifacts is also done for Web 2.5 projects. The result from
				merging the following Servlet class:
				<br />
				<br />
				<img src="javaee/servletCode.png" alt="Servlet with java annotations" />
				<br />
				<br />
				will result in the following deployment descriptor node:

			<description>
				A new wizard is introduced for generating EJB 3.0 Session 
				Bean classes and interfaces. The following features can be 
				highlighted:
