Liberty activate @MessageDriven

Question

I want to activate custom message listener on liberty application server .

this is my code :

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

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

and this is server.xml :

and my activation specification :

public class DandelionActivationSpec implements ActivationSpec {

    private ResourceAdapter resourceAdapter;

    @Override
    public void validate() throws InvalidPropertyException {
    }

    @Override

        return resourceAdapter;
    }

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

Liberty application server result this log on console :

[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.        

outbound resource adapter working without any problem , but inbound does not receive any message !
I read this links before asking this question but can not understand how can fix this problem :
Link 1
Link 2
Link 3
What part of configuration/Code has problem ?

UPDATE:
I change configuration to this :

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

now receive this error on console :

Answer 1

Iranians have a proverb that says: a seeker is a finder
Finally after about 10 days search in internet and wrote simple codes . I found how can fix this problem .
Depend on application server , Message Endpoint should not created on endpointActivation method .
actually TomEE Application server does not result any exception on this code but liberty application server result this exceptions.
I wrote few simple application and published on github.
you can compile and run this application on both TomEE or Liberty.
I will publish more examples in the future, so you can use it too.
