javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class HelloWServlet
extends WServlet

This class demonstrates how to run a WComponent from a Servlet. Simply extend WServlet and implement the method getUI() to return a WComponent. In this case we return a really simple WComponent called a WLabel. Of course you could return a complex component that represents an entire web application.

To see it work, run this class (it has a main), start a browser and enter the url "http://localhost:8080/".
