無法實例化類：org.apache.qpid.jndi.PropertiesFileInitialContextFactory

我在寫一個發送消息的Qpid客戶端。我使用的示例代碼：無法實例化類：org.apache.qpid.jndi.PropertiesFileInitialContextFactory

private void runTest() throws Exception { 
    Properties properties = new Properties(); 
    properties.load(this.getClass().getResourceAsStream("helloworld.properties")); 
    Context context = new InitialContext(properties);        

    ConnectionFactory connectionFactory = (ConnectionFactory) context.lookup("qpidConnectionFactory");    
    Connection connection = connectionFactory.createConnection();     
    connection.start();                

    Session session = connection.createSession(true, Session.SESSION_TRANSACTED); 
    Queue queue = (Queue) context.lookup("myqueue");        

    MessageConsumer messageConsumer = session.createConsumer(queue);    
    MessageProducer messageProducer = session.createProducer(queue);    

    TextMessage message = session.createTextMessage("Hello world!");     
    messageProducer.send(message); 
    session.commit(); 

    message = (TextMessage)messageConsumer.receive();        
    session.commit(); 
    System.out.println(message.getText()); 

    connection.close();                
    context.close();                 
}

附帶的配置是：

java.naming.factory.initial = org.apache.qpid.jndi.PropertiesFileInitialContextFactory 
connectionfactory.qpidConnectionFactory = amqp://guest:[email protected]/?brokerlist='tcp://localhost:61111' 
queue.myqueue = queue1

，我得到的錯誤是：

看起來它是無法初始化屬性文件的上下文。

我有一個ActiveMQ實例在端口61111上本地運行。屬性文件確實在我的CLASSPATH中。我還能在這裏錯過什麼？

你有lib文件夾中正確的所有必要的庫嗎？ – Stultuske

我的IDE抱怨的唯一庫是'java.jmx。*'。所以我加了他們。 –

你使用的是什麼Qpid JMS客戶端，這似乎是一個較老的客戶端，而不是最新的官方Qpid JMS客戶端：http://qpid.apache.org/components/jms/index.html –
