DWR

Hi there , I am using dwr & spring in my application, here is my configurations

  <dwr:controller id="dwrController" debug="true"/>
    <dwr:config-param name="crossDomainSessionSecurity" value="false">
    </dwr:config-param>


         <bean id="dwrUrlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
       <property name="alwaysUseFullPath" value="true"/>
        <property name="mappings">
            <props>
                <prop key="/dwr/**/*">dwrController</prop>
                <prop key="/engine.js">dwrController</prop>
                <prop key="/util.js">dwrController</prop>
                <prop key="/interface/**">dwrController</prop>
                <prop key="/call/**">dwrController</prop>
            </props>
        </property>
    </bean>

 <bean id="ajaxUtils" class="com.realdevelopment.project.util.AjaxUtils">
        <dwr:remote javascript="AjaxFacade">
            <dwr:include method="getStateList"/>
        </dwr:remote>
        <property name="stateDAO">
            <ref bean="stateDAO"/>
        </property>
    </bean>

When i run the application the application server(resin 3-14) throw an exception who says it can not create dwrController bean. If i define dwrController in applicationContext like the other beans , i get this Error

Error: java.lang.SecurityException: No class by name: AjaxFacade
uk.ltd.getahead.dwr.DWRServlet: Sent 501

It's so critical for me to solve this problem.

I would appreciate if you can help me .
Thank you so much and Good Luck
