Access JSTL tag from code inside of forEach loop

Question

Is it possible to access JSTL's forEach variable via code from within the loop?

<c:forEach items="${elements}" var="element">
    <% element.someMethod(); %>
</c:forEach>

Well, I believe "element" is stored in the page context.

<c:forEach items="${elements}" var="element">
    <% ((Element) pageContext.getAttribute("elements")).someMethod(); %>
</c:forEach>

Just out of idle curiosity, where'd you find this method of access?

I've put things in session and request contexts many times for use in a JSP. Plus I knew that the page context is like them.

minor fix: pageContext.getAttribute("element") instead of pageContext.getAttribute("elements")

Edit following the correction of the example:

Yes, it is possible to access the var inside the c:forEach

Here's an example:

<c:forEach items="${elements}" var="element">
    ${((Element)element).someMethod()}
</c:forEach>

See c:forEach in the JSTL Documentation.
