1选择 File|New|Other
2在弹出框中选 MyEclipse|Web|Web Project新建web项目
3选择 File|New|Other
4在弹出框中选 MyEclipse|Web|Servlet 根据提示创建servlet
修改HelloServlet.java文件
修改doGet和doPost两个方法，代码如下
/**
* The doGet method of the servlet. <br>
*
* This method is called when a form has its tag value method equals to get.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setCharacterEncoding("UTF-8");
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
out.println("<HTML>");
out.println("<meta http-equiv=\"content-type\" content=\"test/html; charset=UTF-8\">");
out.println(" <HEAD><TITLE>A Servlet</TITLE></HEAD>");
out.println(" </BODY>");
String requestURI = request.getRequestURI();
out.println("<form action='" + requestURI + "' method='post'>");
out.println("请输入您的名字：<input type='test' name='name'/>");
out.println("<input type='submit' />");
out.println("</form>");
out.println("");
String name = request.getParameter("name");
if(name!= null && name.trim().length()>0){
out.println("您好，<b>"+name +"</b>.欢迎来到java Web世界");
}
out.println("</BODY>");
out.println("</HTML>");
out.flush();
out.close();
}
/**
* The doPost method of the servlet. <br>
*
* This method is called when a form has its tag value method equals to post.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doGet(request, response);
}
保存后部署tomcat ，myeclipse自带tomcat
在状态栏中（如下图）
选择第一个
部署好后 启动tomcat
启动后，打开浏览器，输入地址即可
http://localhost:8080/firstWeb/servlet/HelloServlet（实际情况可能不同）
