how to get camel cxfrs rsServer endpoint resource class invoked

Issue

we have a camel cxfrs route and a rsServer endpoint binds to a java class:

<bean id="serviceClass" class="com.test.helloworld.HelloWorldImpl"/>

<camelcxf:rsServer id="serverEndpoint"  address="http://localhost:9090/helloWorld" loggingFeatureEnabled="true">
    <camelcxf:serviceBeans>
        <ref bean="serviceClass" />
    </camelcxf:serviceBeans>
</camelcxf:rsServer>

<camelContext id="helloWorld" xmlns="http://camel.apache.org/schema/spring">
    <route>
        <from uri="cxfrs:bean:serverEndpoint"/>
        <log message="${camelId} Befor calling service, the message is ${body}"/>
        <to uri="direct:transform"/>
      </route>

      <route>
          <from uri="direct:transform"/>
          <bean ref="HelloWorldResponseTransformer" method="transform"/>
      </route>

When the route was executed the "serverClass" was never called and the route failed silently without any error.
