Question

I have been looking how to implement a thing in struts2 jstl but it is impossible for me to find the way.

When I load the jsp page from the action, I have a list of String lists.

I want to create as divs as elements have the list, but inside every div, I want to create as links as the third element of the sub-list.

So I use the s:iterator tag to parse the list. But I don’t know how to iterate “${item[2]}” times inside the first iterator.

The code would be something like this:

<s:iterator value="functions" var="item" status="stat">
        <span class="operation">${item[1]}</span>
        <div id="${item[0]}">
            <s:for var $i=0;$i<${item[2]};$i++>
                <a href="#" id="link_$i">Link $i</a>
            </s:for>
        </div>
</s:iterator>

Where I have put the s:for tag is where I would like to iterate “${item[2]}” times…

Anyone can help me?

Thank you very much in advance,

Make sure you’ve got the JSTL core library in scope in your JSP page:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

And simply use <c:forEach>. Something like this:

<c:forEach var="i" begin="0" end="${item[2] - 1}">
    <a href="#" id="link_${i}">Link ${i}</a>
</c:forEach>
