Spring 3.1.1.Release. RequestMappingHandlerMapping Autowired issue - spring

Question

I'm trying to add a WADL method to my Spring Web Service application. I'm following the instructions on a number of pages/posts on the topic here and other help sites on the net.
However, my app keeps failing on the auto wire of the RequestMappingHandlerMapping.
The error is:
Error creating bean with name 'wadlController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping net.my.app.ws.thing.WadlController.handlerMapping; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
I've done everything I can think of and search out even added:
mvc:annotation-driven
But the app was entirely annotation drive already, so that didn't seem right.
What else could I be missing? Is it a problem with Spring 3.1.1?

Here is the code for the top section of my controller. I did get it working by auto-wiring the ApplicationContext. However, I don't really like that solution.
package net.stuff.stuff.stuff;
import java.lang.annotation.Annotation;
import java.lang.reflect.Method;
import java.util.Map;
import java.util.Set;
import javax.servlet.http.HttpServletRequest;
import javax.xml.namespace.QName;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.http.MediaType;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.method.HandlerMethod;
import org.springframework.web.servlet.mvc.condition.ProducesRequestCondition;
import org.springframework.web.servlet.mvc.method.RequestMappingInfo;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;
import net.stuff.wadl.*;
#Controller
#RequestMapping("/application.wadl")
public class WadlController {
private static final Logger log = Logger.getLogger(WadlController.class);
#Autowired
private ApplicationContext ctx;
#RequestMapping(method = RequestMethod.GET, produces = { "application/xml" })
public #ResponseBody WadlApplication generateWadl(HttpServletRequest request) {
RequestMappingHandlerMapping handlerMapping = ctx.getBean(RequestMappingHandlerMapping.class);
WadlApplication result = new WadlApplication();
WadlDoc doc = new WadlDoc();
doc.setTitle("REST Service WADL");
result.getDoc().add(doc);
WadlResources wadResources = new WadlResources();
wadResources.setBase(getBaseUrl(request));
if (handlerMapping == null) {
log.error("handlerMapping is null in WadlController???");
return null;
}
