Question

我试图运行一本书中的一个简单的HornetQ示例（HornetQ Messaging Developers Guide），但得到错误消息。我没有使用maven，因为我想坚持书中给出的例子。HornetQ独立服务器在命令行中正常启动。我只是想向HonretQ服务器发送一条消息

package chapter01;

import javax.jms.JMSException;
import javax.naming.NamingException;

public class ECGMessageConsumerProducerExample {

    public static void main(String[] args) throws NamingException, JMSException {
        // TODO Auto-generated method stub


         javax.naming.Context ic = null;
         javax.jms.ConnectionFactory cf = null;
         javax.jms.Connection connection = null;
         javax.jms.Queue queue = null;
         javax.jms.Session session = null;
         com.mongodb.Mongo m;
         com.mongodb.DB db;
         String destinationName = "queue/DLQ";


         java.util.Properties p = new java.util.Properties();
         p.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,
         "org.jnp.interfaces.NamingContextFactory");
         p.put(javax.naming.Context.URL_PKG_PREFIXES,
         "org.jboss.naming:org.jnp.interfaces");
         p.put(javax.naming.Context.PROVIDER_URL, "jnp://localhost:1099");
         ic = new javax.naming.InitialContext(p);


         cf = (javax.jms.ConnectionFactory)ic.lookup("/ConnectionFactory");
         queue = (javax.jms.Queue)ic.lookup(destinationName);
         connection = cf.createConnection();
         session = connection.createSession(false, javax.jms.Session.AUTO_ACKNOWLEDGE);
         connection.start();


         String theECG = "1;02/20/2012 14:01:59.010;1020,1021,1022";
         javax.jms.MessageProducer publisher = session.createProducer(queue);
         javax.jms.TextMessage message =
         session.createTextMessage(theECG);
         publisher.send(message);
         System.out.println("Message sent!");
         publisher.close();





    }

}

尽管我添加了书中提到的所有罐子，但我得到了以下错误：

我还添加了一些我发现与此主题相关的jar，但没有解决问题

是否有产生错误的原因

Answer 1

您需要hornetq-corejar，下载并使用它
