Estou tentando chamar um serviço na minha aplicação web via flex. e exibe a mensagem:

There is no Action mapped for namespace /messagebroker and action name amf

O projeto utiliza struts e inseri o seguinte no webxml:

<servlet>
	<servlet-name>MessageBrokerServlet</servlet-name>
	<servlet-class>flex.messaging.MessageBrokerServlet</servlet-class>
	
	<init-param>
		<param-name>services.configuration.file</param-name>
		<param-value>/WEB-INF/flex/services-config.xml</param-value>
	</init-param>

	<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
	<servlet-name>MessageBrokerServlet</servlet-name>
	<url-pattern>/messagebroker/*</url-pattern>
</servlet-mapping>
