我的源文件:
bean.jsp的内容:
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<!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=gb2312">
<title>使用bean</title>
</head>

<body>
<center>
<table border="5">
<tr>
<th>使用javabean!</th>
</tr>
</table>
</center>
<p>
<jsp:useBean id="test" scope="page" class="ch10.SimpleBean"/>
<jsp:setProperty name="test" property="message" value="你好，jsp!"/>
<h1>Message:<i>
<jsp:getProperty name="test" property="message"/>
</i></h1>
</p>
</body>
</html>

SimpleBean.java的内容:
package ch10;
public class SimpleBean{
private String message="no message";
public String getMessage(){
return(message);
}
public void setMessage(String message){
this.message=message;
}
}

调试的结果就是上面的问题,请各位高手指点啊

SimpleBean.java似乎没问题
那就是JSP调用上出错了，每包含进来
