项目环境：
JDK1.5
ActiveMQ5.2
所用的包都是ActiveMQ自带的。引用的包如下图：
package stujms.p2ptxt;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;
/**
* 消息发送者

* @author leizhimin 2009-8-13 17:01:48
*/
public class MySender {
public static void main(String[] args) {
ApplicationContext ctx = new ClassPathXmlApplicationContext("/applicationContext.xml");
JmsTemplate template = (JmsTemplate) ctx.getBean("jmsTemplate");
Destination destination = (Destination) ctx.getBean("destination");
template.send(destination, new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage("发送消息：Hello ActiveMQ Text Message！");
}
});
System.out.println("成功发送了一条JMS消息");
}
}package stujms.p2ptxt;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.TextMessage;
/**

*
* @author leizhimin 2009-8-13 17:02:04
*/
public class MyReceiver {
public static void main(String[] args) throws JMSException {
ApplicationContext ctx = new ClassPathXmlApplicationContext("/applicationContext.xml");
JmsTemplate template = (JmsTemplate) ctx.getBean("jmsTemplate");
Destination destination = (Destination) ctx.getBean("destination");
while (true) {
TextMessage txtmsg = (TextMessage) template.receive(destination);
if (null != txtmsg)
System.out.println("收到消息内容为: " + txtmsg.getText());
else
break;
}
}

</beans>运行发送端三次：
成功发送了一条JMS消息
Process finished with exit code 0
然后再运行接收端一次：
收到消息内容为: 发送消息：Hello ActiveMQ Text Message！
收到消息内容为: 发送消息：Hello ActiveMQ Text Message！
收到消息内容为: 发送消息：Hello ActiveMQ Text Message！继续测试发现，接收端接收一条消息后不退出程序，而是继续等待，一旦有消息发送过来，就获取到，然后输出！
发一张图看看：
