public abstract class DaemonHttpServlet
extends HttpServlet
A superclass for HTTP servlets that wish to accept raw socket connections. DaemonHttpServlet starts listening for client requests in its init() method and stops listening in its destroy() method. In between, for every connection it receives, it calls the abstract handleClient(Socket client) method. This method should be implemented by the servlet subclassing DaemonHttpServlet. The port on which the servlet is to listen is determined by the getSocketPort() method.

Methods

o init 
 public void init(ServletConfig config) throws ServletException
Begins a thread listening for socket connections. Subclasses that override this method must be sure to first call super.init(config).

Parameters:
config - the servlet config
Throws: ServletException
if a servlet exception occurs
Overrides:
init in class GenericServlet
o getSocketPort 
 protected int getSocketPort()
Returns the socket port on which the servlet will listen. A servlet can change the port in three ways: by using the socketPort init parameter, by setting the DEFAULT_PORT variable before calling super.init(), or by overriding this method's implementation.

Returns:
the port number on which to listen
o handleClient 
 public abstract void handleClient(Socket client)
Handles a new socket connection. Subclasses must define this method.

Parameters:
client - the client socket
o destroy 
 public void destroy()
Halts the thread listening for socket connections. Subclasses that override this method must be sure to first call super.destroy().

Overrides:
destroy in class GenericServlet
