我編寫了消息驅動bean。我對JMS的新東西，並試圖學習消息驅動的豆。主要是EJB 3.x規範。我正在嘗試部署爲下面的類創建的jar。嘗試部署消息驅動bean時在Tomee日誌中出現Null Point異常
import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.Message;
import javax.jms.MessageListener;
@MessageDriven(name="xxx", activationConfig = {
@ActivationConfigProperty(propertyName = "destination",
propertyValue = "/queue/helloQueue"),
@ActivationConfigProperty(propertyName = "destinationType",
propertyValue = "javax.jms.Queue")
})
public class JMSListner implements MessageListener {
@Override
public void onMessage(Message arg0) {
// TODO Auto-generated method stub
System.out.println("message received");
}
}
tomee.xml如下
<?xml version="1.0" encoding="UTF-8"?>
<tomee>

獲得一個例外，當我開始的startup.bat
