Spring 3.1 no xml, just configuration not working

So I'm trying to implement things mentioned in Spring's 3.1 blog post about From XML to @Configuration, but it doesn't want to work as supposed. Here is the web.xml (and that's the only xml) I'm using and the MvcFeatures and MvcBeans more or less are the same as in the blog just added few my beans.

<?xml version="1.0" encoding="UTF-8"?>
<web-app 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_1.xsd"
version="3.1">

<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>
<param-name>contextClass</param-name>
<param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
</init-param>

<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
com.example.config.MvcFeatures
com.example.config.MvcBeans
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

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

<welcome-file-list>
<welcome-file></welcome-file>
</welcome-file-list>

</web-app>


When trying to launch this thing up I get these messages in console:

21 Mar 2011 00:52:58,203 INFO org.springframework.web.context.support.AnnotationConfigWebApplicationContext []: No annotated classes found for specified class/package [com.example.config.MvcFeatures]
21 Mar 2011 00:52:58,203 INFO org.springframework.web.context.support.AnnotationConfigWebApplicationContext []: No annotated classes found for specified class/package [com.example.config.MvcBeans]


Any ideas what could be wrong? From what I understand i think it doesn't like the contextConfigLocation param values.

EDIT: Adding the MvcFeatures in case it helps..

@FeatureConfiguration
public class MvcFeatures {

/**
* Enables the Spring MVC @Controller programming model.
*/
@Feature
public MvcAnnotationDriven annotationDriven(ConversionService conversionService) {
return new MvcAnnotationDriven().conversionService(conversionService)
.argumentResolvers(new CustomArgumentResolver());
}

/**
* Maps '/' requests to the 'home' view.
*/
@Feature
public MvcViewControllers viewController() {
return new MvcViewControllers("/", "index");
}

/**
* Enables Spring's component scanning feature.
*/
@Feature
public ComponentScanSpec componentScan() {
return new ComponentScanSpec("com.example.controllers").excludeFilters(
new AnnotationTypeFilter(Configuration.class), new AnnotationTypeFilter(
FeatureConfiguration.class));
}
}

Answer

Try

    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            com.example.config.**
        </param-value>
    </init-param>

Or set the delimiters accordantly to the docs:

Configuration locations must consist of one or more comma- or space-delimited 
fully-qualified @Configuration classes. Fully-qualified packages may also 
be specified for component-scanning
