开发消息驱动bean(Queue/Topic)
1.配置目标地址(cmcc-service.xml),Jboss使用一个XML文件配置队列地址，文件的取名格式应遵守*-service.xml
2.编写服务器消息的发送者(QueueSender,TopicSender)
3.编写客户端接收者(QueueMessageDriverBean,TopicMessageDriverBean1,TopicMessageDriverBean2)
4.把QueueSender\TopicSender\QueueMessageDriverBean\TopicMessageDriverBean1\TopicMessageDriverBean2这几个java文件打成jar(MessageDriverBean.jar)包发布到jboss下,jboss-4.2.3.GA-jdk6\jboss-4.2.3.GA\server\default\deploy下
/*
QueueSender是PTP的发送者
TopicSender是pub/sub的发送者
QueueMessageDriverBean 是PTP的接收者,点对点(point-to-point，简称 PTP)
TopicMessageDriverBean1、TopicMessageDriverBean2是 pub/sub的接收者,发布/订阅(publish/subscribe,简称 pub/sub)
<attribute name="JNDIName">属性指定了该目标地址的全局JNDI名称。如果你不指定JNDIName属性，jboss会为你生成一个默认的全局JNDI，
其名称由“queue”+“/”+目标地址名称组成。另外在任何队列或主题被部署之前，应用服务器必须先部署Destination Manager Mbean
,所以我们通过<depends>节点声明这一依赖

输出结果是
运行QueueSender: cn.cmcc.message.QueueMessageDriverBean您好，这是我的第一个消息驱动queue Bean
运行TopicSender:
cn.cmcc.message.TopicMessageDriverBean1您好，这是我的第一个消息驱动Topic Bean
cn.cmcc.message.TopicMessageDriverBean2您好，这是我的第一个消息驱动Topic Bean
