本文通过一个具体的示例展示了如何使用JSP页面结合JavaBean来展示学生信息列表。该示例包括了example.jsp文件的全部代码以及Student.java文件的内容，实现了动态获取并展示学生信息的功能。

example.jsp文件：

<%@ page language="java" import="java.util.*,com.neu.Student" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">

Student.java文件：

package com.neu;

public class Student {
    private String name;
    private String gender;
    private int age;
    public Student() {
        super();
    }
    public Student(String name, String gender, int age) {
        super();
        this.name = name;
        this.gender = gender;
        this.age = age;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getGender() {
        return gender;
    }
    public void setGender(String gender) {
        this.gender = gender;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
