Question

我正在尝试远程连接到JBOSS EAP 6.2中嵌入的HornetQ上配置的主题。我尝试过不同的方法，但都给了我同样的错误：

javax.jms.JMSException: Failed to create session factory
at org.hornetq.jms.client.HornetQConnectionFactory.createConnectionInternal(HornetQConnectionFactory.java:676)
at org.hornetq.jms.client.HornetQConnectionFactory.createTopicConnection(HornetQConnectionFactory.java:196)

我按照了这个快速入门的信息：Jboss Eap Quickstart: helloworld-jms

按照我的代码：

try {
    final Properties env = new Properties();
    env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jboss.naming.remote.client.InitialContextFactory");
    env.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
    env.put(Context.PROVIDER_URL, "remote://localhost:4447");
    env.put(Context.SECURITY_PRINCIPAL, "testuser");
    env.put(Context.SECURITY_CREDENTIALS, "testpassword");

    Context context = new InitialContext(env);
    TopicConnectionFactory factory = (TopicConnectionFactory) context.lookup("jms/RemoteConnectionFactory");
    Topic topic = (Topic) context.lookup("jms/topic/myTopic");


    Connection connection = factory.createTopicConnection("testuser", "testpassword"); // The Error occurred here
    connection.start();
    Session session = connection.createSession(false, TopicSession.AUTO_ACKNOWLEDGE); 
    MessageProducer producer = session.createProducer(topic);

    Message message = session.createTextMessage("My Test Message");

    producer.send(message);

    System.out.println("It Worked!");
} catch (Exception e) {
    System.out.println("It Failed!");
    e.printStackTrace();
}

我使用的是带有默认配置的独立式全ha配置文件。

我在代码上做错了吗？或者我是否有任何与默认配置不同的配置？

您是否使用与您正在使用的JBoss EAP版本一起提供的相同HornetQ库编译了客户端代码？您必须知道版本兼容性问题不允许不同HornetQ版本的互操作性。

经过大量的研究和测试，我解决了这个问题。首先，我将jboss-as-jms-client-bom-7.2.0的依赖性更改为：

<dependency>
    <groupId>org.jboss.as</groupId>
    <artifactId>jboss-as-jms-client-bom</artifactId>
    <version>7.1.2.Final</version>
    <type>pom</type>
</dependency>

另外，我更改了代码以使用这种不同的方法连接到服务器：

Connection connection = null;
Session session = null;
Formatter formatter = new Formatter();
Map<String, Object> connectionParams = new HashMap<String, Object>();
connectionParams.put(TransportConstants.PORT_PROP_NAME, 5445);
connectionParams.put(TransportConstants.HOST_PROP_NAME, "localhost");

TransportConfiguration transportConfiguration = new TransportConfiguration(
    NettyConnectorFactory.class.getName(), connectionParams);

try {
    HornetQConnectionFactory cf = HornetQJMSClient
        .createConnectionFactoryWithHA(JMSFactoryType.CF, transportConfiguration);

    connection = cf.createConnection("testuser", "testpassword");

    connection.start();
    session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

    Topic topicTarifas = session.createTopic("tarifas.01101");
    MessageProducer producer = session.createProducer(topicTarifas);

    Message message = session.createTextMessage("My Test Message");

    producer.send(message);

    System.out.println("It Worked!");
} catch (Exception e) {
    System.out.println("It Failed!");
    e.printStackTrace();
}

希望这可能对其他人有用：）
