java - 如何用java连接MQ并发送数据

Question

我已在我的计算机 (imqbrokerd.exe) 中运行 ActiveMQ 并获得以下详细信息。我用

我正在使用下面的java程序连接到这个队列。

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Hashtable;
import javax.jms.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class QueueSendLinear {


    public static void main(String args[]) throws JMSException, NamingException {
         // Defines the JNDI context factory.
         final String JNDI_FACTORY="weblogic.jndi.WLInitialContextFactory";

         // Defines the JMS context factory.
         final String JMS_FACTORY="jms/TestConnectionFactory";

         // Defines the queue.
         final String QUEUE="jms/TestJMSQueue";

         QueueConnectionFactory qconFactory;
         QueueConnection qcon;
         QueueSession qsession;
         QueueSender qsender;
         Queue queue;
         TextMessage msg;
         String xml = "Sample XML comes here!! ";

         String url = "t3://<MachineName>:7676";
         Hashtable env = new Hashtable();
         env.put(Context.INITIAL_CONTEXT_FACTORY, JNDI_FACTORY);
         env.put(Context.PROVIDER_URL, url);
         InitialContext ic =  new InitialContext(env);

         qconFactory = (QueueConnectionFactory) ic.lookup(JMS_FACTORY);
         qcon = qconFactory.createQueueConnection();
         qsession = qcon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
         queue = (Queue) ic.lookup(QUEUE);
         qsender = qsession.createSender(queue);
         msg = qsession.createTextMessage();
         qcon.start();
         msg.setText(xml);
         qsender.send(msg);
         qsender.close();
         qsession.close();
         qcon.close();

    }

}

这里有问题...

a. JNDI_FACTORY、JMS_FACTORY、QUEUE、url 中的值应该是什么？它们代表什么？b. url 中的“t3://”是什么意思？这是一个协议(protocol)吗？如果是这样，主动 MQ 应该给出什么？

仅供引用，我遇到了以下错误

Oct 01, 2015 7:20:58 PM com.sun.corba.se.impl.naming.namingutil.CorbalocURL badAddress

[更新#1]:

当我使用下面的代码时，出现以下错误。我已附上我的 activeMQ 队列详细信息的图像。我知道我使用的网址是错误的。您能帮我找到合适的吗？

希望这有帮助..我已将 JMS 服务器名称作为参数传递。并且应该导入WLS库jar

private static final String CONNECTION_FACTORY_NAME ="connection factory name goes here";  

private static final String TOPIC_NAME = "Topic Name goes here";


private static final String SERVER_URL_PREFIX = "t3://";
private static final String SERVER_URL_SUFFIX = ".url.com:port";
private static final String USER = "";
private static final String PASSWORD = "";

private static final String LOCAL_DIRECTORY = "C:\\tmp\\poslog\\";


public static void main(String args[]) throws JMSException,
        NamingException, IOException, InterruptedException {

    System.out.println("start" + new Date());
    // INITIALIZE
    System.out.println("creating context for " + args[0]);
    Hashtable<String, String> properties = new Hashtable<String, String>();
    properties.put(Context.INITIAL_CONTEXT_FACTORY,
            "weblogic.jndi.WLInitialContextFactory");
    properties.put(Context.PROVIDER_URL, SERVER_URL_PREFIX + args[0] +      SERVER_URL_SUFFIX);
//properties.put(Context.SECURITY_PRINCIPAL, USER);
//properties.put(Context.SECURITY_CREDENTIALS, PASSWORD);
    InitialContext ctx = new InitialContext(properties);
    TopicConnectionFactory connectionFactory = (TopicConnectionFactory) ctx
            .lookup(CONNECTION_FACTORY_NAME);
    TopicConnection connection = connectionFactory.createTopicConnection();
    TopicSession session = connection.createTopicSession(false, 0);
    Topic topic = (Topic) ctx.lookup(TOPIC_NAME);
    TopicPublisher sender = session.createPublisher(topic);
