I want to use the count from the JSTL forEach loop, but my code doesnt seem to work.
<c:forEach items="${loopableObject}" var="theObject" varStatus="theCount">
<div id="divIDNo${theCount}">
</div>
</c:forEach>
produces
<div id="divIDNojavax.servlet.jsp.jstl.core.LoopTagSupport$1Status@5570e2" >

varStatus is what you want! You declare a new variable within the main forEach JSP block which will allow you to access the internal loop counter of the for-each loop. Then you can call a number of methods on that object to be able to do conditional processing.
The <c:for each > is an iteration tag used for repeating the nested body content for fixed number of times or over the collection. These tag used as a good alternative for embedding a Java while, do-while, or for loop via a scriptlet.
The variable set by varStatus is a LoopTagStatus object, not an int. Use:
<div id="divIDNo${theCount.index}">
To clarify:
${theCount.index} starts counting at 0 unless you've set the begin attribute${theCount.count} starts counting at 1

you'd use any of these:
JSTL c:forEach varStatus properties
