Difference between Servlet?s context and config object

Servlet Context

In servlet programming, the servlet context is the environment where all the servlet runs. Every variable stored in the servlet context is accessable to all the servlets running in that context. The servlet container creates a ServletContext object that you can use to access
information about the servlet's environment. Every application can have only one context and all the servlets communicates with each other through this context by using the context parameters.


ServletConfig

A servlet configuration object used by a servlet container used to pass information to a servlet during initialization. Every servlet can have its servlet config object to use init parameters.
