Hello,
could you please ensure that your JSP has a tag library declaration for
JSTL core:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core"; prefix="c" %>
Can you check please the generated HTML code of the page? If if contains
untranslated JSTL tags, than something is wrong with the JSTL tag lib
declaration.
The check ${empty actusList.size} is not quite correct as the
actusList.size is of type int. To check if the container list is empty
use: ${actusList.size == 0}
By the way, does the container list is getting displayed at all?
Kind regards
Sergiy
