Develop Web applications

 

Before you begin

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:

• Use one of the available integrated development environments (IDEs). IDE tools automatically generate significant parts of the servlet and JavaServer Pages (JSP) code, and Hypertext Markup Language (HTML) files. They also contain integrated tools for packaging and testing the Web application components. The IBM WebSphere Application Developer product is the recommended IDE. For more information, see the documentation for that product.

• If you decide to develop Web components without an IDE, we need at least an ASCII text editor. We can also use tools available in the Java Software Development Kit (SDK) and in this product 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 <install_root>\lib directory.

   For example, to compile a servlet running on the Windows NT version of WebSphere Application Server, specify

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

   To compile that same servlet on the Windows NT version of WebSphere Network Deployment, specify

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

3. (Optional) Disable JSP runtime compilation, if necessary.

 

What to do next

Assemble the application components in one or more Web modules.
