Свобода активирует @MessageDriven

Я хочу активировать пользовательский прослушиватель сообщений на сервере приложений Liberty.

это мой код:

@MessageDriven(name = "Receiver")
public class Receiver implements InboundListener {

    @Override
    public void receiveMessage(String message) {
        System.out.println("Message Received : " + message);
    }
}      

и это server.xml:

<?xml version="1.0" encoding="UTF-8"?>

    <webContainer disableXPoweredBy="true"/>
    <applicationManager autoExpand="true"/>
    <applicationMonitor updateTrigger="mbean"/>
</server>    

и моя спецификация активации:

@Activation(messageListeners = InboundListener.class)
public class DandelionActivationSpec implements ActivationSpec {

    private ResourceAdapter resourceAdapter;

    @Override
    public void validate() throws InvalidPropertyException {
    }

    @Override
    public ResourceAdapter getResourceAdapter() {
        return resourceAdapter;
    }

    @Override
    public void setResourceAdapter(ResourceAdapter ra) throws ResourceException {
        this.resourceAdapter = ra;
    }
}       

и ra.xml:

Сервер приложений Liberty приводит к этому журналу на консоли:

[WARNING ] CNTR4015W: The message endpoint for the Receiver message-driven bean cannot be activated because the dandelion-war-0.1-SNAPSHOT/Receiver activation specification is not available. The message endpoint will not receive messages until the activation specification becomes available.        

Адаптер исходящих ресурсов работает без проблем, но входящие не получают никаких сообщений!
Я прочитал эти ссылки, прежде чем задавать этот вопрос, но не могу понять, как можно решить эту проблему:
Ссылка 1
Ссылка 2
Ссылка 3
В какой части конфигурации/кода возникла проблема?

ОБНОВЛЕНИЕ:
я меняю конфигурацию на это:

<activationSpec id="dandelion-web/Receiver">
    <properties.dra/>
</activationSpec>
<webApplication id="dandelion-web"
                location="dandelion-web.war"
                name="dandelion-web">
    <classloader classProviderRef="dra"/>
</webApplication>     

теперь получите эту ошибку на консоли:
