A web application is a collection of Java servlets, JSPs, HTML pages, classes and other resources. All the resources are stored in a directory, and all requests to that directory run the application. Use the pages under the Web Applications tab of the Virtual Server Manager to deploy and edit web applications for a specific virtual server.
For more information on web applications and the deployment descriptor file for web applications,sun-web.xml, see the Sun Java System Web Server 6.1 SP8 Administrator’s Configuration File Reference.
