Question

我是JMS的新手，我正在尝试加载一个connectionFactory。我遵循了几个教程，但由于某些原因它似乎不起作用，每次我尝试'.lookup'connectionfactory时我都会得到一个例外。我正在使用JBoss7.1。

以下是我正在尝试获取connectionFactory的类：

public class QueueSend extends Frame implements ActionListener {  

  private QueueConnectionFactory qconFactory;
  private QueueConnection qcon;
  private QueueSession qsession;
  private QueueSender qsender;
  private Queue queue;
  private TextMessage msg;

  private TextField tf=new TextField();
  private Button send=new Button("Send");

  public QueueSend(){
      super("Queue Sender");
      setLocation(150,50);
      setSize(200,100);
      add(tf);
      add(send,BorderLayout.SOUTH);
      send.addActionListener(this);
      send.setEnabled(false);
      addWindowListener(new WindowAdapter(){
                          public void windowClosing(WindowEvent w){
                              send("quit");
                              close();
                              System.exit(0);
                          }
      });
      setVisible(true);
      init();
  }

  public void init(){
    try{

        InitialContext ctx = getInitialContext();
        qconFactory = (QueueConnectionFactory) ctx.lookup("ConnectionFactory");

        queue = (Queue) ctx.lookup("java:/queue/text");

    qcon = qconFactory.createQueueConnection();

    qsession = qcon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);

    qsender = qsession.createSender(queue);

    qcon.start();

    send.setEnabled(true);
}catch(NamingException e1){e1.printStackTrace();
}catch(JMSException e2){e2.printStackTrace();}
  }


  public void actionPerformed(ActionEvent e){
  String message=tf.getText();
  tf.setText("");
  if(message.length()>0)
      send(message);
  }

  public void send(String message){
try{
    //send a message with the given string
    TextMessage textMessage = qsession.createTextMessage(message);
    qsender.send(textMessage);
    // enter text here    
}catch(JMSException e){e.printStackTrace();}
  }

  public void close(){
try{
    qsender.close();
    qsession.close();
    qcon.close();
}catch(JMSException e1){e1.printStackTrace();
}catch(NullPointerException e2){e2.printStackTrace();}
  }

  public static void main(String[] args){
   new QueueSend();    
  }  

  public  InitialContext getInitialContext(){
    Properties properties = new Properties();
    properties.put(Context.URL_PKG_PREFIXES,"org.jboss.ejb.client.naming");
    properties.put(Context.INITIAL_CONTEXT_FACTORY,     "org.jboss.naming.remote.client.InitialContextFactory");
        properties.put("jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT",     "false");
    properties.put("java.naming.provider.url","remote://127.0.0.1:4447");
    properties.put("jboss.naming.client.ejb.context","true");
        properties.put("jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT","false"    );



    try {
        return new InitialContext(properties);
    } catch (NamingException e) {
        System.out.println("Cannot generate InitialContext");
        e.printStackTrace();
    }
    return null;
   }
}

我得到了这个例外：

javax.naming.NameNotFoundException: ConnectionFactory -- service   jboss.naming.context.java.jboss.exported.ConnectionFactory
at org.jboss.as.naming.ServiceBasedNamingStore.lookup(ServiceBasedNamingStore.java:97)

当我从浏览器登录JBoss服务器时，我在'命名'选项卡下找不到'ConnectionFactory'

这是来自standalone-full.xml：

            <jms-connection-factories>
                <connection-factory name="InVmConnectionFactory">
                    <connectors>
                        <connector-ref connector-name="in-vm"/>
                    </connectors>
                    <entries>
                        <entry name="java:/ConnectionFactory"/>
                    </entries>
                </connection-factory>
                <connection-factory name="RemoteConnectionFactory">
                    <connectors>
                        <connector-ref connector-name="netty"/>
                    </connectors>
                    <entries>
                        <entry name="RemoteConnectionFactory"/>
                        <entry name="java:jboss/exported/jms/RemoteConnectionFactory"/>
                    </entries>
                </connection-factory>
                <pooled-connection-factory name="hornetq-ra">
                    <transaction mode="xa"/>
                    <connectors>
                        <connector-ref connector-name="in-vm"/>
                    </connectors>
                    <entries>
                        <entry name="java:/JmsXA"/>
                    </entries>
                </pooled-connection-factory>
            </jms-connection-factories>

我做错了什么？

Answer 1

我发现了问题所在。我的JBoss服务器的默认配置文件是standalone.xml，而connectionFactory是在standalone-full.xml文件中配置的，这是standalone.xml的更完整版本，所以我所要做的就是更改配置文件服务器从standalone.xml到standalone-full.xml，并且可以解决问题：@）〜

Answer 2

对我来说，我试图在远程Widlfly上查找java:jboss/exported/jms/RemoteConnectionFactory。我没有使用错误的java:/jms/RemoteConnectionFactory，而是我需要查找jms/RemoteConnectionFactory （exported之后的文字）。

在JMS上找不到具有JNDI的ConnectionFactory
