What is Servlet context?
Servlet context is created by the container and can be viewed as a shared memory resource for all the servlets for a web application. A servlet context object can be placed in the memory and all other servlets can used this information. For example log files information, dispatching requests etc. Only one servlet context is available for one web application that uses servlets. The web application environment information can also be passed to the init() method. The web container instantiates the servlet context at the time of deploying a web application.
