c:set标签中的var 与value的关联问题!!!

txy821

.jsp加入代码:
<c:set scope="session" value="${page.result}" var="page"></c:set>
<c:set value="${page1.result}" var="page1" scope="session"></c:set>
<c:set value="${page2.result}" var="page2" scope="session"></c:set>
报错:
avax.servlet.jsp.el.ELException: The "." operator was supplied with an index value of type "java.lang.String" to be applied to a List or array, but that value cannot be converted to an integer.
可见这种<c:set>的用法是错误的!!!!!!
