在JSP中使用JAVABEAN 本文介绍了在JSP中使用JavaBean的方法，包括如何纳入JavaBean引用、设置和读取bean属性。通过jsp:useBean、jsp:setProperty和jsp:getProperty动作标记，实现了业务逻辑和表示逻辑的分离，使得Web设计员和程序员的角色更加明确。阅读详情

我用的是eclipse
people.java

public class people {
private String name;
private int age;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}

}

index.jsp

<%@page contentType="text/html;charset=gb2312" %>

<html>
<head></head>
<body>
<form action="show.jsp" method="get">
姓名：<input type="text" name="name">
年龄：<input type="text" name="age">
<p>
<input type=submit value="submit">
</form>
</body>
</html>

show.jsp

<%@page contentType="text/html; charset=gb2312" %>

<jsp:useBean id="user" scope="page" class="people"/>

<jsp:setProperty property="*" name="user"/>

<html>
<body>
<%=user.getName() %>
<p>
<%=user.getAge() %>
</body>
</html>

遇到的问题是:
org.apache.jasper.JasperException: Unable to compile class for JSP:

刚开始以为是class文件路径错了,但好像不是.
请大虾指点......
