JSTL forEach separator

Is there a built in feature in JSTL to output separators while doing foreach?

The task is to output separators (like commas) after each iteration except the last one (or before each except the first). Is there any ELSE tag for foreach?

You may use `varStatus' attribute in EL,

<c:forEach var="foo" items="${foos}" varStatus="loopStatus">${foo}${!loopStatus.last?',':''}</c:forEach>`

<c:forEach items="${myList}" var="item" varStatus="status">
    ${item}<c:if test="${not status.last}">,</c:if>
</c:forEach>

Use the varStatus attribute, which references an object of type LoopTagStatus:

<c:forEach var="foo" items="${foos}" varStatus="loopStatus">
    <c:out value="${foo}"/>
    <c:if test="${!loopStatus.last}"> | </c:if>
</c:forEach>
