Your web.xml is declaring your application as being a Servlet 2.3 compatible web application
```
<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >
```
Expression Language (EL) was introduced in 2.4.

Change that and you should be in business (as long as your container also supports it).

You can find templates for the different versions here.

Just add jstl dependency if it is a maven project.
```
<dependency>
    	<groupId>jstl</groupId>
    	<artifactId>jstl</artifactId>
    	<version>1.2</version>
</dependency>
```
It worked for me.

Your problem is not related to Spring MVC. ${message} is EL (Expression Language). It's a part of Java EE (and a former part of the JSP specification). It does not work on your page for some reason.

Try to replace the beginning of your web.xml with the following:
```
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 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_2_5.xsd">
```

Add this in your jsp page:

<%@ page isELIgnored="false" %>
