Class ReachHostServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

uk.co.westhawk.servlet.ReachHostServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class ReachHostServlet
extends javax.servlet.http.HttpServlet

The ReachHostServlet servlet uses the IsHostReachableBean to see if a host is reachable.

It will hold the connection until it has received the information. Then it will print the date the host went up, following by a nice HTML form which makes it easier to do a next request.

This servlet should be installed on a Java bases webserver. The parameters should be a part of the URL. If no parameters are send, the servlet will use the default values.

Parameters:
• host - the host, default is your localhost
• port - the port, default 161
• comm - the community name, default public

For example:

     http:<servlet URL>?host=localhost&port=161&comm=public
