无法创建从独立Java应用程序到JBoss AS 7消息队列的JMS连接

Question

我已经使用standalone-full.xml配置文件配置了在JBoss AS 7.1.1.FINAL上运行的JMS队列.

然后我编写了一个独立的 Java程序来连接队列并根据JBoss示例代码发送消息.

public class RemoteProducer {

    private static final Logger log = Logger.getLogger(RemoteProducer.class.getName());

    // Set up all the default values
    private static final String DEFAULT_CONNECTION_FACTORY = "jms/RemoteConnectionFactory";
    private static final String DEFAULT_DESTINATION = "jms/queue/test";
    private static final String DEFAULT_USERNAME = "jmstest";
    private static final String DEFAULT_PASSWORD = "fluppy";
    private static final String INITIAL_CONTEXT_FACTORY = "org.jboss.naming.remote.client.InitialContextFactory";
    private static final String PROVIDER_URL = "remote://localhost:4447";

    /**
     * @param args
     */
    public static void main(String[] args) {
        ConnectionFactory connectionFactory = null;
        Connection connection = null;
        Session session = null;
        MessageProducer producer = null;
        Destination destination = null;
        Context context = null;

        try {
            // Set up the context for the JNDI lookup
            final Properties env = new Properties();
            env.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT_FACTORY);
            env.put(Context.PROVIDER_URL, System.getProperty(Context.PROVIDER_URL, PROVIDER_URL));
            env.put(Context.SECURITY_PRINCIPAL, System.getProperty("username", DEFAULT_USERNAME));
            env.put(Context.SECURITY_CREDENTIALS, System.getProperty("password", DEFAULT_PASSWORD));
            context = new InitialContext(env);

            // Perform the JNDI lookups
            String connectionFactoryString = System.getProperty("connection.factory", DEFAULT_CONNECTION_FACTORY);
            log.info("Attempting to acquire connection factory \"" + connectionFactoryString + "\"");
            connectionFactory = (ConnectionFactory) context.lookup(connectionFactoryString);
            log.info("Found connection factory \"" + connectionFactoryString + "\" in JNDI");

            String destinationString = System.getProperty("destination", DEFAULT_DESTINATION);
            log.info("Attempting to acquire destination \"" + destinationString + "\"");
            destination = (Destination) context.lookup(destinationString);
            log.info("Found destination \"" + destinationString + "\" in JNDI");

            // Create the JMS connection, session, producer, and consumer
            connection = connectionFactory.createConnection(System.getProperty("username", DEFAULT_USERNAME), System.getProperty("password", DEFAULT_PASSWORD));
            session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
            producer = session.createProducer(destination);
            connection.start();

            // TODO send messages

        } catch (NamingException e) {
            e.printStackTrace();
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}

不幸的是,调用connectionFactory.createConnection失败并出现JMS异常(HornetQException[errorCode=3 message=Timed out waiting to receive cluster topology. Group:null):

问题:没有涉及集群,两个程序都在同一台机器上运行,我没有配置任何IP地址.有没有人知道我在JBoss配置中可能缺少什么？

任何提示欢迎:-)

我通过检查和更改项目的Maven依赖项解决了这个问题.

有了这个Maven依赖,该程序按预期工作:

<dependency>
    <groupId>org.jboss.as</groupId>
    <artifactId>jboss-as-jms-client-bom</artifactId>
    <version>7.1.1.Final</version>
    <type>pom</type>
</dependency>
