c:if syntax error

I have a session object "CART" that is a List, In my JSP I have

<c:if test="${!empty sessionScope.CART and sessionScope.CART.size() > 0}">
// proess things
</c:if>

But it complains the syntax error. I don't know why ?? All I want to do is to check if the CART is not null and has more than one element..

Thanks.

You cannot call instance methods in the EL. In other words, no calls to size().

By the way, you don't need to do the size check anyways. The empty operator will return true if the operand is null or if it is empty.
