spring 3 mvc annotation-driven with DWR annotations

I am currently working on a new project that uses Spring 3 MVC Annotation-driven model. I had used DWR on previous projects successfully, but without using annotations, and relying on XML configuration.

After having played around with Spring's annotation driven model, I found it much easier than it's XML counterpart, and so I was determined to get DWR working in the same manner.

mvc-config.xml

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

    </mvc:interceptors>

    <!-- Saves a locale change using a cookie -->
    <bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver" />

    <!-- Resolves view names to protected .jsp resources within the /WEB-INF/views directory -->

    </bean>

And then to verify that it DWR is integrated correctly you can visit:
