How do I have the JSP-generated servlet subclass my own custom servlet class, instead of the default?
One should be very careful when having JSP pages extend custom servlet classes as opposed to the default one generated by the JSP engine. In doing so, you may lose out on any advanced optimization that may be provided by the JSPengine. In any case, your new superclass has to fulfill the contract with the JSPngine by: Implementing the HttpJspPage interface, if the protocol used is HTTP, or implementing...

What is the difference between GenericServlet and HttpServlet?
GenericServlet is for servlets that might not use HTTP, like for instance FTP service.As of only Http is implemented completely in HttpServlet. The GenericServlet has a service() method that gets called when a client request is made.

What is the servlet life cycle?
Each servlet has the same life cycle:A server loads and initializes the servlet (init())The servlet handles zero or more client requests (service())The server removes the servlet (destroy()) (some servers do this step only when they shut down)
Sandhya.Kishan

Every servlet follows the same cycle
*The servlet is initialized by calling the init () method.
*The servlet calls service() method to process a clients request.
*The servlet is terminated by calling the destroy() method.
*Finally, servlet is garbage collected by the garbage collector of the JVM.

Servlets provide a way to generate dynamic documents that is both easier to write and faster to run. It is efficient, convenient, powerful, portable, secure and inexpensive. Servlets also address the problem of doing server-side programming with platform-specific APIs. they are developed with Java Servlet API, a standard Java extension.

Servlets are platform independent.Each request handled by CGI needs a sapreate process With java more than one request can be handled with threads.
