The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory
Get rid of any servletcontainer-specific libraries such as jsp-api.jar in your /WEB-INF/lib folder. This exception indicates that you’ve put servletcontainer-specific libraries of a container which supports only Servlet 2.4 / JSP 2.0 or older in there (the getJspApplicationContext() method was introduced in Servlet 2.5 / JSP 2.1). This is a major mistake. Those libraries don’t … Read more

How to avoid using scriptlets in my JSP page?
I think it helps more if you see with your own eyes that it can actually be done entirely without scriptlets. Here’s a 1 on 1 rewrite with help of among others JSTL (just drop jstl-1.2.jar in /WEB-INF/lib) core and functions taglib: <%@ taglib uri=”http://java.sun.com/jsp/jstl/core” prefix=”c” %> <%@ taglib uri=”http://java.sun.com/jsp/jstl/functions” prefix=”fn” %> <html> <head> <title>My … Read more
