how to get the size of a HashMap using jstl

Question

Is there any way to get the size of a Map using JSTL ? I tried with ${myMap.size} but it's not working..

Answer 1

got the solution: Use jstl functions.

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

then use like this:

  <c:if test="${fn:length(myMap) > 1 }">

Answer 2

${myMap.size}

isn't working because it gets translated to myMap.getSize() by the EL parser.

Try:

${myMap.size()}

It should work.

Answer 3

The JSTL length function works on a Collection but not sure if it will work on a Map. Might be worth a try.
