public SampleBean() {
}
public void setID(String id){
this.id=id;
}
public void setAge(String age){
this.age=age;
}
public String getID(){
return id;

谢谢大家了
[解决办法]
setID getID 改成setId,getId看看
[解决办法]
谁告诉你可以随便的
JAVA是区分大小写的
[解决办法]
jsp:
<%@ page contentType= "text/html;charset=gb2312 " language= "java "%>
<jsp:useBean id= "smpBean " class= "ch06.SampleBean "/>
<html>
<head>
<title> 一个简单的Bean页面 </title>
</head>
<body>
<%
smpBean.setAge( "11);
%>
<%= smpBean.getAge();%>
</body>
</html>
试试
[解决办法]
<%= smpBean.getAge()%>
