Jboss7 JMS demo
最近温习了下EJB和JMS，整理了下思路，和大家分享下P2P和Pub/Sub的demo
；JBoss 7 集成了HornetQ，JMS可以在HornetQ中间件运行，有时间在和大家分享关于HornetQ的文章。
1.下载Jboss 7并配置运行环境 http://www.jboss.org/jbossas/downloads
2.增加testjms用户（用以jms链接时使用），在jboss的bin目录下运行add-user.bat，如下：
3.修改启动配置文件，使用standalone-full.xml启动jboss服务器
4.例子：修改Jboss配置文件standalone-full.xml，找到hornetq-server节点，在该节点下的jms-destinations确定含有以下配置：
P2P demo
Pub/Sub demo
这个在jboss-client.jar 包可以找到，看你用的jboss版本了，我这里用的是JBoss AS7
