Redeploy I mean when you go to Services tab, servers, glassfish, app, web app, right click the selected app and UNDEPLOY. But usually the 'Clean and Build' & 'Run' solve most problems.
Well, a needed class cannot be found when you run the app (java.lang.ClassNotFoundException). - Have you ever worked with JSTL? - Are the JSTL jars included in the project / application server? - Have you declared <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"; %> in the beginning of the jsp file? Check the topics above.
