Class GenericServlet

Defines a generic, protocol-independent servlet. To write an HTTP servlet for use on the Web, extend HttpServlet instead.

The GenericServlet class implements the Servlet interface and, for convenience, the ServletConfig interface. Servlet developers typically subclass GenericServlet, or its descendent HttpServlet, unless the servlet needs another class as a parent.
The GenericServlet class was created to make writing servlets easier. It provides simple versions of the life-cycle methods init and destroy, and of the methods in the ServletConfig interface. It also provides a log method, from the ServletContext interface. The servlet writer must override only the service method, which is abstract.
To write a generic servlet, you need only override the abstract service method.
