How can I get element from list in JSTL (not forEach)?

Question

I'm in a forEach and would like to get an element (from listName) with proportional id as forEach loop element.

<% i=0; %>
<c:forEach var="account" items="${ctx.model.accounts}">
    <c:out value="${listName.get(${i})}" />
    <% i++; %>
</c:forEach>

Is this even possible?

I mean ${listName.get(${i})} is of course wrong, but how can I get it.

You don't need scriptlets to achieve that.

<c:forEach var="account" items="${ctx.model.accounts}" varStatus="loopStatus">
    <c:out value="${listName[loopStatus.index]}" />
</c:forEach>

But the fact that you have two parallel lists is, IMHO, a smell. Why don't you have a single list, where each element would allow access to the account and to the corresponding element in listname?

${listName[i]} will give you the element from listName.

Check Get specific element in a list or array using EL for details.

Got warning: `cannot resolve property or method 'i' (dynamic property?)` – y07k2 Mar 16 '17 at 10:38

Better use `varStatus` as suggested by JB. – Ajinkya Mar 16 '17 at 10:40
