A Web application is a unit of deployment for interrelated Web content, JSPs, and Java servlets. The Web application contains static files, servlet and JSP implementation classes, and a deployment descriptor that describes how the files, servlets, and JSPs are configured on the host server. The deployment descriptor also allows you to configure application-specific HTTP properties, such as MIME types and per-file security constraints. To tie it all together, a Web application provides an abstract naming convention for the JNDI names of database connections and EJBs.
A Web application represents a subset of the files available on a Web server. Each Web application has a context path that forms a prefix for URLs that access the JSPs, servlets, and static pages; for example, http://myHost/Finance.
Each Web application also has a deployment directory in the server’s file system where the Web application’s files are deployed. In EAServer, the deployment directory for the Web application Finance is this subdirectory in your EAServer installation:
/deploy/webapps/Finance
