这个sess_use.jsp为什么运行出错？
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
</head>

<body>
<center>

存取session数据
 
<hr />
 
<%
int num=0;
Object obj=session.getAttribute("Num");
if (obj==null)
{session.setAttribute("Num",String.valueOF(num));
}
else
{
num=Integer.parseInt(obj.toString());
num+=1;
session.getAttribute("Num",String.valueOf(num));
}
%>
</center>

session中的Num的值为：
<%=num%>

</body>
</html>
错误信息是：
org.apache.jasper.JasperException: Unable to compile class for JSP
