The jsp page gets the length of the list collection passed from the background

Import function tag library in jsp page

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

The length of the list is:

${fn:length(list)}

Instead of using ${list.size} to get the length of the list
in the jsp page.
