Creating Web 2.0 enabled Web projects

Web 2.0 enabled Web projects hold all of the Web resources that are created and used when developing a Web 2.0 Web application.

Install the WebSphere® Application Server Feature Pack for Web 2.0.

To create a Web 2.0 enabled dynamic Web project:

1. In the Enterprise Explorer view, right-click and select

   New | Other | Dynamic Web Project | Next. The New Dynamic Web Project wizard opens.

2. In the

   Project name field, type the name of your Web project.

3. Select a Target Runtime from the drop down list.

   Note: This field will be disabled if a target runtime had been previously set. To enable this field, you can do one of the following:

   • Specify a new EAR Project Name then select a

     Target Runtime.

   • Select an existing EAR project from the list that uses the target runtime that you want to use.

4. Click the

   Modify button beside the Configurations drop down list.

5. On the Project Facets page, select the

   Web 2.0 check box and click OK to apply the Web 2.0 facets.

   A project facet is a specific unit of functionality that you can add to a project when that functionality is required. When a project facet is added to a project, it can add natures, builders, classpath entries, and resources to a project, depending on the characteristics of the particular project. Web 2.0 facets define the characteristics of your Web 2.0 enabled Web application. The Web 2.0 facets specify the requirements and constraints that apply to your Web 2.0 project.

   Table 1. Web 2.0 facets

   Facet name	Description
   Web 2.0	Enables support for the runtime components in the WebSphere Feature Pack for Web 2.0: AJAX Proxy, Dojo Toolkit, and Server-side technologies.
   Ajax Proxy	Enables support for the WebSphere AJAX Proxy.
   Dojo Toolkit	Enables Dojo capabilities.
   Server-side technologies	Adds the libraries for server-side technologies such as Feed support, Web remoting, Web messaging, and JSON4J to your Web project.

   By enabling the Ajax proxy facet, your Web project is configured to broker client requests from multiple domains while using Ajax. The Ajax proxy included in the WAS Feature Pack for Web 2.0 eliminates browser security concerns with cross-domain scripting when combining internal and external services.

   By enabling the Dojo Toolkit facet, your Web project is configured to develop Dojo Web applications. The Dojo Toolkit included in the WAS Feature Pack for Web 2.0 includes the open source Dojo toolkit and additional IBM® extensions to the base Dojo Toolkit, including libraries for ATOM (ATOM Syndication Format) data access, analog and bar gauges, and simplified access for SOAP Web services.

   By enabling the server-side technologies facet, your Web project is configured for both development and runtime support for the WAS Feature Pack for Web 2.0. All of the required JAR files are added to the Java™ Build Path for your project and the deployment descriptor.
