Myeclipse下怎样运行servlet程序

1.配置tomcat
2.新建一个项目工程，我的项目名称为myServlet
3.把tomcat下的lib目录中的servlet-api.jar这个驱动包放入新建项目myServlet下的lib目录中，在myServlet/WebRoot/WEB-INF下
4.在项目中新建一个TestServlet类，代码如下:
import java.io.IOException;
import javax.servlet.Servlet;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class TestServlet extends HttpServlet{
/*
* 重写service方法
*/
@Override
protected void service(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.getWriter().write("hello,this is my first servlet!");
}

}
5.找到项目中的web.xml配置文件，修改如下配置:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>firstServlet</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>first</servlet-name>
<!-- 类名的全称，点击类名，右键复制全名称类名-->
<servlet-class>TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>first</servlet-name>
<url-pattern>/first</url-pattern>
</servlet-mapping>
</web-app>
6.启动tomcat，在浏览器中输入:http://localhost:8080/myServlet/first
7.浏览器中显示: hello,this is my first servlet!
8.配置成功
