Developing J2EE Web Applications

The process of developing, deploying and running a Web application consists of the following main phases:

1. Developing the Web components - writing the Java code. This may include:
   1. Developing servlets
   2. Developing JSP pages
   3. Developing filters
   4. Programming additional features of Web components - HTTP sessions, failover capabilities, and so on.
2. Configuring Web components by editing the deployment descriptors.
3. Packaging the Web components along with any static resources and helper classes referenced by them.
4. Deploying the Web application to the J2EE Engine.
5. Running the application.

The topics that are included in this section of the documentation examine the pure development aspects of the process of developing a J2EE web application (in terms of APIs you can use, description of the life-cycle of the different components, any proprietary implementation issues that affect the process, and so on). If you are rather looking for a "hands-on" tour along this process, refer to the Implementing a Web Application in the Getting Started section of the Development Manual. There you can read how to develop a simple web application using the SAP NetWeaver Developer Studio.
