Assembling Web applications

 

Assembling Web applications

Assemble a Web module to contain servlets, JavaServer page (JSP) files, and related code artifacts. (Group enterprise beans, client code, and resource adapter code in separate modules). After assembling a Web module, you can install it as a standalone application or combine it with other modules into an enterprise application.

This article assumes that you have created and unit tested Servlets, JavaServer Pages (JSP) files and other Web components that you want to assemble in an enterprise application and deploy onto an application server.

Use the Application Server Toolkit (AST) or Rational Web Developer assembly tool to assemble a Web module in any of the following ways:

Although you can input various properties for Web archives, available properties are specific to the Servlet, JSP, and J2EE specification level.

  1. Start an assembly tool.

  2. If you have not done so already, configure the assembly tool for work on J2EE modules. Ensure that J2EE and Web capabilities are enabled.

  3. Migrate WAR files created with the Assembly Toolkit, Application Assembly Tool (AAT) or a different tool to an AST or Rational Web Developer assembly tool. To migrate files, import your WAR files to the assembly tool.

  4. Create a new Web module.

  5. Copy code artifacts (such as servlets) from one Web module into a new Web module.

ResultA Web project is migrated or created. Files for the Web project are shown in the Project Explorer view under Enterprise Applications and Web Projects .

 

What to do next

You can now deploy your Web project to an application server.
