I added jstl-1.2.jar to my lib folder, then I included:
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
on top of my JSP file and still It says `Unknown tag (c:forEach).
welcome.jsp
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%#taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

I want to load CSS on the JSP page. But I am getting empty pageContext.request.contextPath in JSP page. I am using this approach because if I move the page around in different directories within the templates or JSP then I should not need to keep on making changes to paths of referred CSS or js files.
Jsp page is as below
<%# page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<%# taglib prefix = "x" uri = "http://java.sun.com/jsp/jstl/xml" %>
<%# taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core" %>
<%# taglib prefix = "fmt" uri = "http://java.sun.com/jsp/jstl/fmt" %>
<%# taglib prefix = "fn" uri = "http://java.sun.com/jsp/jstl/functions" %>
<%# taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%# taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%#page isELIgnored="false"%>

I am using Spring version 2.6.0. Along with the following dependencies in pom.xml-
spring-boot-starter-web
spring-boot-starter-tomcat (scope: provided)
tomcat-embed-jasper (scope: provided)
jstl
As per Spring Boot, pageContext is Implicit. Then what could be going wrong here?
Any help or suggestions would be appriciated.
check if remove <%#page isELIgnored="false"%>
if not work test : request.getContextPath()
after all see this link :
pageContext.request.contextPath not working
I want to show the Authenticated user's firstname and lastname. I put related code segment in Header.jsp and include it in two other jsp pages, Index.jsp and News.jsp.
When Header.jsp included in News.jsp, it works correctly and displays Authenticated user's firstname and lastname, but when it's include in Index.jspm it doesn’t show anything.
My pages structure looks like blow:
Header.jsp
<%# page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%# taglib prefix="sec" uri="http://www.springframework.org/security/tags" %>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<div class="usertext">
<span id="loginedUserFullname">
<sec:authorize access="isAuthenticated()">
<sec:authentication property="principal.firstname" />
<sec:authentication property="principal.lastname" />
<span class="welcome">welcome</span>
<a class="logout" href='/view/cpanel/Logout.jsp'>(loge out)</a>
</sec:authorize>
</span>
</div>
</nav>
Index.jsp
<%# page contentType="text/html; charset=UTF-8" language="java" pageEncoding="UTF-8" isELIgnored="false"%>

whats wrong with <sec> that doesn't work in the Index.jsp?
Is it possible that Index.jsp does not require the user the be authenticated but News.jsp does?
I am able see the warning in a jsp file for the anchor tag.
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<p>Return to Main List</p>

</html>
In the line <p>Return to Main List</p> its showing a warning:
WebContent/WEB-INF/jsp/${mainUrl} not found.
I can understand about the c:url tag but in the href with the place holder ${mainUrl}, then its showing warning in all the files which I have placed like this format. Please neeed suggestion to fix this or why am getting this?
The tag doesn't work... Jsp doesn't print anything... Could I debug jsp page in Eclipse?

controller are in MyController.java
#Controller
public class MyController {
#RequestMapping(value="/my")
public String getMyHomePage(Model model) {
LinkedList<String> listOfMyFriends = new LinkedList<String>();
listOfMyFriends.add("friend1");
listOfMyFriends.add("friend2");
listOfMyFriends.add("friend3");
listOfMyFriends.add("friend4");
model.addAllAttributes(listOfMyFriends);
return "my";
}
}
Replace the line before the return with
model.addAttribute("listOfMyFriends", listOfMyFriends);
When you do a model.addAllAttributes(listOfMyFriends);
It Copies all attributes in the supplied Collection into this Map, using attribute name generation for each element.
Attribute name generation is done using the method : Conventions.getVariableName()
So, if you are not certain what will be the generated attribute name, use
model.addAttribute("listOfMyFriends", listOfMyFriends);
So that you can access the list of your friends using the key "listOfMyFriends"
Add listOfMyFriends to the Model as follows :
model.addObject("listOfMyFriends ", listOfMyFriends );
