Class DaemonHttpServlet

java.lang.Object
  HttpServlet
      com.oreilly.servlet.DaemonHttpServlet

Direct Known Subclasses:

RemoteDaemonHttpServlet

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.
