我在class中建了个bean：SimpleBean.class，在ROOT/web建了个testbean.jsp:
<%@page contentType="text/html;charset=gb2312" language="java"%>
<jsp:useBean id="test"scope="application" class="SimpleBean"/>
<html>
<head>
<title>Simple Bean</title>
</head>
<body>
running
<hr>
<center>
<%=test.getMessage()%>
</center>
</body>
</html>
然后在浏览器中输入 http://210.41.121.166:8080/web/testbean.jsp
可问题是怎么出现了以下错误：
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
