最近初学javaweb，下面将介绍如何创建一个简单的javaweb实例。

首先把eclipse以及相应的Java jdk和Tomcat服务器配置完成。然后在eclipse里面新建Dynamic Web Project项目件。

在建好的项目中的doget方法中添加如下的代码：

package king;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.swing.JOptionPane;/**public class Firstking extends HttpServlet {
 * Servlet implementation class Firstking */@WebServlet("/Firstking")private static final long serialVersionUID = 1L;    public Firstking() {
private static final Object[] OK = null;           /**     * @see HttpServlet#HttpServlet()     */        super();protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated constructor stub    }/** * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) *//**
// TODO Auto-generated method stub//response.getWriter().append("Served at: ").append(request.getContextPath());response.getWriter().write("hello world!");}protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response) */// TODO Auto-generated method stubdoGet(request, response);}
}

这样运行该Java文件就能够看到熟悉的hello word。哈哈。
