Question

我有一个使用Wildfly 10 Final和JSF 2.2.9的动态Web项目。我试图通过Message Driven Bean发送消息。

但是如果我尝试在Wildfly上启动Web应用程序，我会收到以下错误：

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);
    }
}

尝试发送消息的类：

@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");    
  }  
  ....  
}

我使用Standalone-full.xml为JMS-Support启动了WildFly服务器并插入了以下行：

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

任何人都可以帮助我吗？是配置错误还是类似的？

感谢。最好的问候。

对于DJTust，我在调用jmsContext.createProducer（）。send（queue，“Hello”）之后找到了解决NullPointer的答案。你也要添加beans.xml。见Nikolai Schreier在JMSContext NullPointer Exception - wildfly 8.2.0 default queue

未安装Wildfly 10 Final JMS所需服务
