Question

我正在尝试开发一个在Glassfish 3上运行的JMS应用程序。 Eclipse Indigo是我的IDE。我试图运行 this example 。如果您觉得有必要，我会在这里复制代码。我不明白我应该怎么做JNDI。我通过管理控制台创建了具有确切指定名称的两个所需资源，但是我得到了这个例外：

根据我的阅读，在服务器上，InitialContext应该自动运行。

我做错了什么？

Answer 1

在构造InitialContext时，您需要提供一些描述如何从JNDI服务器访问和获取对象的属性。

主要是您需要提供一个标记供应商实现的属性，另一个指向数据存储位置的属性，您可能需要指定其他安全性或供应商特定的属性。

在你的情况下（glassfish），我认为需要设置以下属性：

// the initial context factory, choosing the glassfish implementation
env.setProperty("java.naming.factory.initial","com.sun.enterprise.naming.SerialInitContextFactory");
// glassfish's server location
env.setProperty("org.omg.CORBA.ORBInitialHost", "<host name or IP>");
env.setProperty("org.omg.CORBA.ORBInitialPort", "<port number>"); // default is 3700

Answer 2

结果是我的类路径的JAR问题。所需的JAR是问题中指定的JAR，另外两个是接受的答案 here ，即：gf-client-module.jar，imqjmsra.jar和{{1} }。

Answer 3

我希望这段代码能帮到你，我的环境： JEE6 + glassfish3V

 private static ConnectionFactory connectionFactory;
 private static Queue queue;
 public static void main(String[] args) throws NamingException {
      Connection connection = null;
      Session session = null;
      MessageConsumer consumer = null;
      TextMessage message = null;

      Properties env = new Properties();

      //glassfish3V
      env.put(Context.PROVIDER_URL, "iiop://localhost:8080");
      InitialContext jndi = new InitialContext(env);
      connectionFactory = (ConnectionFactory) jndi.lookup("jms/ConnectionFactory");
      queue = (Queue) jndi.lookup("jms/Queue"); // put your Queue here


      try {
           connection = connectionFactory.createConnection();
           session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
           consumer = session.createConsumer(queue);
           connection.start();

           while (true) {
                Message m = consumer.receive(1);

                if (m != null) {
                     if (m instanceof TextMessage) {
                          message = (TextMessage) m;
                          System.out.println(
                                  "Reading message: " + message.getText());
                     } else {
                          break;
                     }
                }
           }
      } catch (JMSException e) {
           System.err.println("Exception occurred: " + e.toString());
      } finally {
           if (connection != null) {
                try {
                     connection.close();
                } catch (JMSException e) {
                }
           }
      }
 }
