I have a Dynamic Web Project with Wildfly 10 Final and JSF 2.2.9. I tried to send a message via Message Driven Bean.

But if I try to start the web application on Wildfly I get the following errors:

23:57:53,971 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("deploy") failed - address: ([("deployment" => "MyApplication.war")]) - failure description: {

}

WebSocketDrivenBean

@MessageDriven(
    activationConfig = { @ActivationConfigProperty(
            propertyName = "destination", propertyValue = "java:/jms/queue/WebSocketDrivenQueue"), @ActivationConfigProperty(
            propertyName = "destinationType", propertyValue = "javax.jms.Queue")
    }, 
    mappedName = "java:/jms/queue/WebSocketDrivenQueue")
   @Named
   public class WebSocketDriven implements MessageListener {
    @Inject
    @WSJMSMessage
    Event<Message> jmsEvent; 

    public WebSocketDriven() {
    }

    public void onMessage(Message message) {
        jmsEvent.fire(message);
    }
}

QueueSenderSessionBean

@Stateless
public class QueueSenderSessionBean {

    @Resource(mappedName = "java:/jms/queue/WebSocketDrivenQueue")
    private Queue myQueue;
    @Inject
    private JMSContext jmsContext; 

    public void sendMyText(String message){
        jmsContext.createProducer().send(myQueue, message);
    }
}

And the class which tries to send the message:

@Named  
@ClientEndpoint(encoders={JsonEncoder.class}, decoders={JsonDecoder.class})  
public class MyTestApplication implements Serializable{  
  private static final long serialVersionUID = 1L;  
  Session userSession = null;  

  @Inject  
  private QueueSenderSessionBean senderBean;  

   ....  

  @OnMessage  
  public void onMessage(WebSocketMessage message) {  
      this.senderBean.sendMyText("Hello");    
  }  
  ....  
}

I started the WildFly server with the standalone-full.xml for JMS-Support and inserted the following line:

<jms-queue name="WebSocketDrivenQueue" entries="java:/jms/queue/WebSocketDrivenQueue />

Can anybody help me? Is there a config error or something similar?

Thanks. Best regards.

That could be just naming issue. I would try to use lookup param for queue injection instead of QueueSenderSessionBean. Like @Resource(lookup = "java:/jms/queue/WebSocketDrivenQueue"). I think that the jms queue names are not mapped to java:comp/env space (not sure to be honest, check docs.oracle.com/javaee/7/api/javax/annotation/…)chalda
Yes, thanks. That's it. the präfix java:/ was required. I edited my first post. But now I get a NullpointerException in my WebSocket class MyTestApplication on this.senderBean.sendMyText("Hello"); Any ideas, why?DJTrust
Isn't there some error in server.log? It seems that there is a trouble with injection of SLSB bean to the websocket endpoint. As I do not have much experience in this field I did a quick search on net and found out this answer: stackoverflow.com/questions/20872300/… I hope it helps.chalda

To DJTust, I found the answer for solving NullPointer after calling jmsContext.createProducer().send(queue, "Hello"). You've to add beans.xml too. See Nikolai Schreier answered at JMSContext NullPointer Exception - wildfly 8.2.0 default queue
