public void init(ServletConfig config) throws ServletException
Servlet
The servlet container calls the init
method exactly once after instantiating the servlet.
The init
method must complete successfully
before the servlet can receive any requests.
The servlet container cannot place the servlet into service
if the init

public void service(ServletRequest request, ServletResponse response) throws ServletException, java.io.IOException
Servlet
This method is only called after the servlet's init()
method has completed successfully.
The status code of the response always should be set for a servlet that throws or sends an error.
Servlets typically run inside multithreaded servlet containers that can handle multiple requests concurrently. Developers must be aware to synchronize access to any shared resources such as files, network connections, and as well as the servlet's class and instance variables. More information on multithreaded programming in Java is available in the Java tutorial on multi-threaded programming.

HttpJspPage
If a superclass is specified using the extends attribute, that superclass may choose to perform some actions in its service() method before or after calling the _jspService() method. See using the extends attribute in the JSP_Engine chapter of the JSP specification.

This method gives the servlet an opportunity to clean up any resources that are being held (for example, memory, file handles, threads) and make sure that any persistent state is synchronized with the servlet's current state in memory.
