DWR appfuse struts2 integration fail

[foward]

Hello,

I have several questions related how integrate DWR and appfuse with Struts2 framework. I try to do some integration but I have an error :
PWC1231: Servlet.service() para el servlet dwr-invoker desencadenó una excepción
java.lang.NoClassDefFoundError: com/opensymphony/xwork/config/ConfigurationException .....

I google a lot to find how integrate dwr but I cannot find the solution...( Only I look that I have to put the DWRAction.java in my source code but I dont know if this is correct : http://kkbear.javaeye.com/blog/125130 ...)

Here the configurations files:
------ view.JSP -----
...
        <script type="text/javascript" src="<c:url value="/dwr/interface/DWRAction.js"/>"></script>
        <script type="text/javascript" src="<c:url value="/scripts/DWRActionUtil.js"/>"></script>
        <script type='text/javascript' src="<c:url value="/dwr/engine.js"/>"></script>
        <script type='text/javascript' src="<c:url value="/dwr/util.js"/>"></script>

</head>


        <script language="JavaScript" type="text/javascript">
                var cbf = function done(data)
                {
                        alert('came here');
                }
                function doValidate() {
                   
                        DWRActionUtil.execute({
                  namespace:'default',
          action:'crearEncuesta',
          method:'list',
          executeResult:'true'
                                                        }, {}, cbf);
                        alert('OH YEAH BABE');
                }
        </script>

------ dwr.xml  ----
<dwr>
    <allow>

        <create creator="none" javascript="DWRAction">
           
            <include method="execute"/>
        </create>
        <convert converter="bean" match="org.directwebremoting.webwork.ActionDefinition">
           
        </convert>
        <convert converter="bean" match="org.directwebremoting.webwork.AjaxResult"/>

    </allow>
</dwr>

---- struts.xml ----

 <action name="crearEncuesta" class="formAction">
            <result>/WEB-INF/pages/encuestas/createForm.jsp</result>
            <result name="error">/WEB-INF/pages/encuestas/formList.jsp</result>
  </action>

----- web.xml -----
 <servlet>
        <servlet-name>dwr-invoker</servlet-name>
        <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>
        <init-param>
            <param-name>debug</param-name>
            <param-value>true</param-value>
        </init-param>
    </servlet>
   
    <servlet>
        <servlet-name>xfire</servlet-name>
        <servlet-class>org.codehaus.xfire.spring.XFireSpringServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>dwr-invoker</servlet-name>
        <url-pattern>/dwr/*</url-pattern>
    </servlet-mapping>

Typically you use DWR to integrate with your business layer (Managers)  
and not the web controllers.  It looks like DWR can't call your action  
because the action is called outside of the Struts context.

DWR is more about marshalling direct from your business layer to  
client JavaScript, hence the name.  So if you can't call your business  
class or don't have one,  then perhaps you really want to make an AJAX  
http request to struts instead.  I have had success with Jquery  
calling Struts actions that output JSON results using the JSON plugin.
