我在Wildfly 8.2.0中有一个队列，并使用监听器部署了耳朵。然后我试图从客户端程序发送文本消息到远程队列。在这种情况下，无法查找远程连接工厂。附上程序和错误。
Wildfly上的MDB监听器
import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;
@MessageDriven(activationConfig = {
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
@ActivationConfigProperty(propertyName = "destination", propertyValue = "jms/queue/mdbtest")})
public class ExampleQueueMDB implements MessageListener {
@Override
public void onMessage(Message message) {
if (message instanceof TextMessage) {
try {
System.out.println("----------------");
System.out.println("Received: "
+ ((TextMessage) message).getText());
System.out.println("----------------");
} catch (JMSException e) {
e.printStackTrace();
}
} else {
System.out.println("----------------");
System.out.println("Received: " + message);
System.out.println("----------------");
}
}
}

在第62行创建连接时出现上述错误，
connection = connectionFactory.createConnection(DEFAULT_USERNAME,DEFAULT_PASSWORD);
我不确定，为什么这不起作用。希望这是一个直截了当的案例。如果有不同的方法来查找RemoteConnectionFactory，请告诉我。感谢。
更新
方法2： 如果我使用下面的配置，能够调用任何ejb方法，但仍然为RemoteConnectionFactory查找抛出错误。
// Set up the context for the JNDI lookup
final Properties env = new Properties();
env.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
env.put("endpoint.name", "client-endpoint");
env.put("remote.connections","default");
env.put("remote.connection.default.port","8080");
env.put("remote.connection.default.host","localhost");
env.put("remote.connection.default.username", DEFAULT_USERNAME);
env.put("remote.connection.default.password", DEFAULT_PASSWORD);
env.put("org.jboss.ejb.client.scoped.context",true);
context = new InitialContext(env);
上述更改后出错，

查询错误，第56行，
connectionFactory = (ConnectionFactory) context.lookup(connectionFactoryString);
请提供此问题的任何解决方案。感谢。

从https://developer.jboss.org/thread/265919找到答案。
由于我使用infinispan，我已经使用Wildfly 8.2.0的infinispan版本（6.0.2）作为客户端程序。但Wildfly使用 HornetQ 2.4.5 ，客户使用 HornetQ 2.2.7 。我在客户端改为HornetQ 2.4.5，一切正常。
