The difference between 1.servletConfig and ServletContext

The difference between 1.servletConfig and ServletContext

• From the deployment point of view, ServletConfig is in the servlet, and ServletContext is under Web-app
• From the code,

  Getservletcontext (). Getinitparameter ("foo"); Getservletconfig (). Getinitparameter ("foo")

• From a usable point of view, ServletConfig is available only to the corresponding servlet, while ServletContext is useful for all servlets and JSPs
