------解决方案--------------------------------------------------------
/inside.jsp(9,1)
inside.jsp第9行，是否使用了jsp:param标签？
------解决方案--------------------------------------------------------
<jsp:forward page="success.jsp" />
------解决方案--------------------------------------------------------
取出的数据 你还要转换格式
转换成String类型的
------解决方案--------------------------------------------------------
- Java code
<jsp:forward page="success.jsp"/>
