activeMQ创建生产者与消费者

普通web项目，未使用maven

配置文件：default.properties，放到conf下就行。

#----  activeMQ配置参数    ----------------------
AMQ_USER = admin
AMQ_PASSWORD = admin
#URL = ActiveMQConnection.DEFAULT_BROKER_URL;
AMQ_URL = failover://tcp://192.168.42.147:61616
AMQ_SUBJECT = ActiveMQ.Demo
#----  activeMQ配置参数    ----------------------

消费者：jmsReceiver

测试类：

package com.cn.cncc.activeMQ;

import javax.jms.JMSException;

import javax.jms.Connection;

/**

public class Test {
	static Connection mqConnection;

	public static void main(String[] args) throws JMSException, Exception {

		sender.close();
		
		
		JmsReceiver receiver = new JmsReceiver();
		receiver.receiveMessage();
		receiver.close();
	}
}

有时会报 NoClassDefFoundError 错误，可将下面两个包放到lib文件夹下，并buildpath.
javax.jms.jar、javax.management.j2ee.jar，
