When running the application the http://localhost/<webapp>/dwr/ does not show the classes/javascripts seen by DWR.
The StaticFilter in web.xml needs to include the dwr/* folder to permit developers to see the beans seen by DWR.

Fix:
Replace the Static filter in web.xml with the following:

<filter>
        <filter-name>staticFilter</filter-name>
        <filter-class>org.appfuse.webapp.filter.StaticFilter</filter-class>
        <init-param>
            <param-name>includes</param-name>
            <param-value>/scripts/dojo/*,/dwr/*</param-value>
        </init-param>
        <init-param>
            <param-name>servletName</param-name>
            <param-value>dispatcher</param-value>
        </init-param>
    </filter>
