JavaBean实例：

新建如下项目——新建包——新建类……

实例一：

一：在tsc包中新建Person类

package tsc;

public class Person {
	String name = "ts";
	int age = 18;

	public Person() { 

	}
	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

}

二：新建jweb4.jsp页面，JavaBean在地址栏中传递参数

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<%@ page import="tsc.*"%>
<%--地址栏中传递参数 --%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
	<jsp:useBean id="persons" class="tsc.Person"></jsp:useBean>
	<jsp:setProperty property="name" name="persons" param="n" />
	<jsp:setProperty property="age" name="persons" param="m" />
	<h1>
		姓名是：<jsp:getProperty property="name" name="persons" /><br> 年龄是：<jsp:getProperty
			property="age" name="persons" />
	</h1>
</body>
</html>

运行结果：
