${} variables not showing - Spring MVC

I´m have a Maven project with Spring MVC, Spring Security and Spring Social.

When I put a message in the jsp, this show ${message} instace of the message.

I have jstl library.

My JSP:

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>

    <script>
        var m = '${message}';
        alert(m);
    </script>

    ${pageContext.request.contextPath}
    <c:out value="${message}"></c:out>
    <br /><br />
    ${message}
    <br /><br />
    ${currentUserConnection.profileUrl}
    <br /><br />

</body>
</html>

My controller:

@Controller
public class LoginController {

    @RequestMapping(value = "/signup**")
    public ModelAndView signupHandler() {

        ModelAndView model = new ModelAndView("home");
        model.setViewName("home");

        model.addObject("message", "aa");

        return model;
    }

}

The web page show ${message} instace of aa. Also alert show ${message} too

What can I be doing wrong? Thanks in advance.

EDIT 1:

The configuration are in Annotations. My viewResolver:

@Bean(name = "viewResolver")
public InternalResourceViewResolver viewResolver() {
    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
    viewResolver.setViewClass(JstlView.class);
    viewResolver.setPrefix(viewPrefix);
    viewResolver.setSuffix(viewSuffix);
    return viewResolver;
}

SOLUTION:

The solution is the version of my web xml need to be greater than 2.5

Thanks @M.Deinum

I also faced the same type of problem in which I put list inside ModelAndView object and tried to show that list on jsp page using foreach loop.

The problem arised because of version of web application I've used Servlet 2.3

I have exhausted my 2 hours, but search and found that adding

<%@ page isELIgnored="false" %>

I would really recommend you update your servlet version. We're coming up on 3.1 right now, doesn't make sense to be on 2.3

solved my problem, please try this.

Make sure that you have correct jsp resolver into your spring context xml.

Like:

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/views/"/>
    <property name="suffix" value=".jsp"/>
</bean>

And proper Dispatcher Servlet configuration in your web.xml:

  <servlet>
    <servlet-name>dispatcher</servlet-name>
        <servlet-class>
               org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
  </servlet-mapping>

And also for old Servlet 2.3 you can add fallow into jsp (see here) or ofc change your web.xml to new one:

<%@ page isELIgnored ="false" %>

In most cases not working EL is related to a wrong version in the web.xml. 

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>

For EL to work the version has to be higher then 2.3. Preferably the highest available for your container. 

<?xml version="1.0" encoding="UTF-8"?>

<web-app
    version="3.0"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

</web-app>
