jsp - How to make EL not to print evaluated expression? -


i want rid of taglib declarations in every jsp page (similar question).

that's why made headr.jsp html header stuff , taglib declarations. want include in every jsp page this:

<%@ include file="/web-inf/include/header.jsp" %>

whose content start with:

<%@ page pageencoding="utf-8" contenttype="text/html; charset=utf-8" %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %> <!doctype html> ... <title>${pagescope.pagetitle}</title>

the problem have page title in header.jsp, want change. need set in jsp page before including header.jsp, can not use c:set, because jstl not declared yet. decided use el put pagetitle in param or somescope map this:

${param.put("pagetitle", "test")}

now problem npe here. sure caused put() returning null when add new entry map, , el tries print null output.

ps: know can use scriptlets, since bad practice, not consider them @ , disabled them in web.xml.
