When serving client requests, various Web components that build a Web application share objects that they have instantiated. To do so, they make them available in certain scopes. At runtime, these scopes are represented by Java objects. The following scopes are available to J2EE Web application developers:

Scope

Object Type

Description

Servlet context

Note

For JSP pages this scope is also called “application” scope.

javax.servlet.ServletContext

This object represents the whole Web application at runtime. It is available to all servlets and JSP pages that build the application.

Request

javax.servlet.ServletRequest

This object represents the current HTTP request. It is available to all components that process the current request.

This object represents the current session of a user. It is available to all components that process requests that are associated with this HTTP session.
