A Web application is a collection of:
Servlets
JSPs
Utility classes
Static documents (HTML, images, sounds, and so on)
Client-side Java applets, and classes
Descriptive metadata ties these elements together. A Web application represents a subset of the files available on a Web server. Each Web application has a:
Context path – forms a prefix for URLs that access the JSPs, servlets, and static pages. For example, http://myhost/Finance.
Deployment directory – a directory in the server’s file system where the Web application’s files are deployed. In EAServer, the deployment directory for Web application wapp is this subdirectory in your EAServer installation:
/deploy/webapps/wapp
