404错误表示找不到相应的网页，也就是说你的Servlet配置不对，你在Web.xml配一下Servlet相关Action等
package com.idv2.learnjsp;import java.io.IOException;
import java.io.PrintWriter;import javax.servlet.GenericServlet;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;public class HelloServlet extends GenericServlet { /**
* 自动生成的序列号
*/
private static final long serialVersionUID = 322156104287226122L; /**
* Servlet启动时调用的函数
*/
public void init() {
System.out.println("init() was called.");
} /**
* 处理客户端的请求
* @param req 客户端请求
* @param res 客户端响应
*/
@Override
public void service(ServletRequest req, ServletResponse res)
throws ServletException, IOException {
System.out.println("service() was called.");
// 指定输出内容以及编码方式
res.setContentType("text/html; charset=UTF-8");
// 获取输出流对象
PrintWriter out = res.getWriter();
// 发送HTML内容
out.println("<html>");
out.println("<head>");
out.println("<title>Hello, Servlet!</title>");
out.println("</head>");
out.println("<body>");
out.println("Hello, Servlet!");
out.println("</body>");
out.println("</html>");
}
/**

public void destroy() {
System.out.println("destroy() was called.");
}
}
配置文件是哪一部分？
