Servlet Context

Servlet Context is a window for a servlet to view it environment. A servlet can use this interface to get information such as initialization parameters for the web application or the servlet container’s version. Every web application has only one ServletContext and it is accessible to all the active resources of that application. It is also used by the servlets to share the data with one another.

Every web application has exactly one instance of javax.servlet.ServletContext . The context is initialized at the time that the web application is loaded. As we have the initialization parameter for servlet we have initialization parameter for servlet context. The servlet of a web application can retrieve these initialization parameter using the methods of the ServeltContext interface.The servlet context initialization parameter are used to specify application wie information.
