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 技术分享

；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： guest 一定要写。
技术分享

3.修改启动配置文件，使用standalone-full.xml启动jboss服务器

Cmd代码

$JBOSS_HOME$\bin>standalone.bat --server-config=standalone-full.xml

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：

Xml代码

<jms-destinations>
<jms-queue name="testQueue">
<entry name="queue/test"/>
<entry name="java:jboss/exported/jms/queue/test"/>
</jms-queue>
<jms-topic name="ServerNotificationTopic">
<entry name="topic/ServerNotification"/>
<entry name="java:jboss/exported/jms/topic/ServerNotification"/>
</jms-topic>
</jms-destinations>

客户端项目用eclipse集成jboss的 j2ee项目。runtime是jboss 7.

另外一定别忘了加入 external lib ：jboss-client-7.1.0.Final.jar (JBOSS_HOME/bin/client)

否则会报错：

javax.naming.NamingException: JBAS011843: Failed instantiate InitialContextFactory

User: acs doesn‘t have permission=‘SEND‘ on address jms.queue.testQueue 权限错误，需要看看：

“jboss-home\stabdalone\configuration\application-roles.properties”

加一句 testjms=guest

其他错误参见：
