[java ee programming] JSTL/EL Exception thrown by a Vector's size attribute

[Juan Diego]

Hi folks!

I am trying to retrieve the "size" attribute from a Vector for
evaluating if there is data stored in there, but it throws me an
exception when I use "${myvector.size gt 0}  why??

This is the code

        <c:if test="${branch.telephones.size gt 0}">
            Tel&eacute;fonos:
            <c:forEach var="telephone" items="${branch.telephones}">
                <c:out value="${telephone}" />
            </c:forEach>
        </c:if>

And it does not have to be with the data retrieved previously, because
I already tested it and everything is alright.

I hope you can help me with this.

Thank you in advance!


PD: I removed the c:if to print directly withouth any validations the
telephone numbers and nothing, it does not print nothing.
