Develop Web applications

 

Design a Web application and the components that it needs.

For general Web application design information, see "Resources for learning."

 

Overview

There are two basic approaches to selecting tools for developing Web applications:

• You can use one of the available integrated development environments (IDEs). IDE tools automatically generate significant parts of the servlet and JavaServer Pages code, and Hypertext Markup Language (HTML) files. They also contain integrated tools for packaging and testing the Web application components.

• If you decide to develop Web components without an IDE, we need at least an ASCII text editor. You can also use tools available in the Java Software Development Kit (SDK) and in WAS to assemble, test, and deploy the Web application components.

The following steps support the second approach, development without an IDE.

 

Procedure

1. If necessary, migrate any pre-existing code to the required version of the servlet and JSP specification.

2. Write and compile the components of the Web application. To access classes that were extended, compile your code using the -classpath option on the javac compiler. This option allows you to reference the j2ee.jar file in the product directory:

   • <install_root>\lib

   To compile that same servlet on the Windows NT version of WebSphere ND, specify:

    javac -classpath D:\Program Files\WebSphere\DeploymentManager\lib\j2ee.jar MyServlet.java
   
   

    

3. (Optional) Disable JavaServer Pages runtime compilation, if necessary.

 

What to do next

Assemble the application components in one or more Web modules.
