HornetQ JMS：java.lang.NoSuchMethodError [英] HornetQ JMS: java.lang.NoSuchMethodError

问题描述

遗憾的是，在尝试使用HornetQ处理JMS服务时，我正在运行表单错误消息以显示错误消息。先前的错误与缺少core.jar文件有关。

但是，我收到以下错误消息：

 线程main中的异常java.lang.NoSuchMethodError：org.hornetq.api.core.client.ClientSessionFactory.copy（）Lorg / hornetq / api / core / client / ClientSessionFactory; 
 at org.hornetq.jms.client.HornetQConnectionFactory.createConnectionInternal（HornetQConnectionFactory.java:612）
 at org.hornetq.jms.client.HornetQConnectionFactory.createConnection（HornetQConnectionFactory.java:116) 
 at org.hornetq.jms.client.HornetQConnectionFactory.createConnection（HornetQConnectionFactory.java:111）
 at chapter01.ECGMessageConsumerProducerExample.main（ECGMessageConsumerProducerExample.java:33）
  

我预计错误是由服务器使用的jar和客户端使用的jar不匹配引起的。但由于我是程序员菜鸟，我真的不知道需要哪些适合的版本的罐子。

解决方案

尝试定义NettyConnectorFactory作为中的连接器jboss参考。

例如在hornetq-configuration.xml文件中：

 < ;连接器及GT; 
< connector name =netty> 
< factory-class> 
 org.hornetq.core.remoting.impl.netty.NettyConnectorFactory 
< / factory-class> 
< param key =portvalue =5446/> 
< / connector> 
< / connectors> 
  

unfortunately while trying to get a JMS service working with HornetQ, I am running form error message to error message. The prior error was related to a missing core.jar file. Prior Error

After all, I am trying to implement a simple producer/consumer example as a jms service. (Based on "HornetQ Messaging Developer's Guide")

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();





    }

}

While facing erros I probably added unneeded jars:

However, I get the following error message:

Exception in thread "main" java.lang.NoSuchMethodError: org.hornetq.api.core.client.ClientSessionFactory.copy()Lorg/hornetq/api/core/client/ClientSessionFactory;
    at org.hornetq.jms.client.HornetQConnectionFactory.createConnectionInternal(HornetQConnectionFactory.java:612)
    at org.hornetq.jms.client.HornetQConnectionFactory.createConnection(HornetQConnectionFactory.java:116)
    at org.hornetq.jms.client.HornetQConnectionFactory.createConnection(HornetQConnectionFactory.java:111)
    at chapter01.ECGMessageConsumerProducerExample.main(ECGMessageConsumerProducerExample.java:33)

I expect the error to be caused by a mismatch between jars used by the server and used by the client. But since I am a programmer noob, I do not really know what exact jars with suitable versions are needed.

解决方案

Try defining NettyConnectorFactory as connector as in jboss reference.

for example in hornetq-configuration.xml file:

<connectors>
    <connector name="netty">
        <factory-class>
            org.hornetq.core.remoting.impl.netty.NettyConnectorFactory
        </factory-class>
        <param key="port" value="5446"/>
    </connector>
</connectors>
