Iterate only few elements inside a jstl foreeach

Question

I have a requirement where I have to itearate over a map element kept in PageContext, inside jstl fore each . And I am also using an iterator inside the option tag. So I need to make sure the fore each loop iterate 1 less then the actual map size of map al, so that my iterator i is not iterated completely.

    select name="interval" id="interval" onchange="comeback()" >

    <% 
    String s="";
    s=(String)portletSession.getAttribute("int1"); 
    %>


     <option value="int">Time Interval</option>
     <c:forEach var="line" begin="0" end="<%= al.size()-1 %>" items="${al}">
     <option <%=((String)((Iterator)portletSession.getAttribute("i")).next()).equals(s)?"selected":" "%>  > <c:out value="${line.value}"/></option> 

    </c:forEach>

    <option value="others" <%=((String)((Iterator)portletSession.getAttribute("i")).next()).equals(s)?"selected":" "%> >> 60 Days </option>
    </select>

I tried using begin end but did not work out. Please help me out.

You can quite easily iterate the Map keys and the Values for each key using standard JSTL. For example: http://stackoverflow.com/questions/29029272/jstl-hashmap-and-dynamic-key/29039563#29039563 — Alan Hay, May 06 '15 at 15:11

end="<%= al.size()-2 %>"

the last element you want should be al.size()-2, according to array's index
