Question

我正在通过视频教程学习J2EE并坚持使用第一个基本的servlet。在视频上页面加载成功，但不在我的浏览器上。作为讲师，我做了一切。服务器运行良好。检查了8080和4848.我也向glassfish添加了servelet，但仍然是错误404.谢谢。

package com.airline.controllers;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet implementation class AddPassenger
 */
@WebServlet("/AddPassenger")
public class AddPassenger extends HttpServlet {
    private static final long serialVersionUID = 1L;

    /**
     * @see HttpServlet#HttpServlet()
     */
    public AddPassenger() {
        super();
        // TODO Auto-generated constructor stub
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

 PrintWriter out = response.getWriter();
 response.setContentType("text/html");
 out.println("<html><body>");

 out.println("<h2>Welcome to My Airlines!!</h2>");

 out.println("</body></html>");


        response.getWriter().append("Served at: ").append(request.getContextPath());
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        doGet(request, response);
    }

}

选择 Glass Fish服务器，右键单击并选择＆＃39; 发布＆＃39;。现在刷新页面，这应该可行。

基本的Eclipse + Glassfish错误Servlet 404
