I've been over Spring's documentation a couple times, but I don't seem to be able to get @Controller, etc annotations to work.
I am loading the dependencies and repositories in my POM (... are my specific values):

In my web.xml, I am setting up the dispatcher servlet:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/servlet-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
And under WEB-INF I have servlet-context.xml (... is my controller package):
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/mvc

<!-- Adds prefix and suffix to returned views -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
I think I must be missing or forgetting something simple. Eclipse doesn't recognize the annotations and maven fails to build the project. Can anyone help me out here?
EDIT
For further clarification, in eclipse, adding the annotation results in:
The import org.springframework cannot be resolved
And running mvn clean install results in:
package org.springframework.stereotype does not exist
And removing the runtime scope results in the following Maven error:
error reading ...\.m2\repository\org\aopalliance\com.springsource.org.aopalliance\1.0.0\com.springsource.org.aopalliance-1.9.9.jar; error in opening zip file
I found the answer to my question in a later post.
Basically, I needed to add the m2eclipse plugin to Eclipse. You can find instructions at http://m2eclipse.sonatype.org/installing-m2eclipse.html if needed. Once this is installed, you can right click on your project in Eclipse and choose Maven > Enable Dependency Management. Then eclipse will be able to recognize imports from your POM dependencies.
So in the end, I had the following. Eclipse recognized everything, Maven correct built and packaged the project, and Tomcat deployed the project successfully.
Here is my web.xml hooking up the dispatcher servlet:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"

Here's my servlet-context.xml enabling the annotations and view resolver:
