1. 监控和管理Broker
Web Console 方式：直接访问ActiveMQ的管理页面：http://localhost:8161/admin，默认的用户名和密码是admin/admin。具体配置在conf/jetty.xml里面，这就是我们前面例子中一直使用的方式。
Hawtio-web Management Console方式：
默认用户名密码是admin/admin
JMX方式。
2. 集成ActiveMQ和Tomcat
ActiveMQ和Tomcat可以很自如的集成在一起使用，而不需要使用JNDI的方式，启动Tomcat的时候就可以启动ActiveMQ，方式如下：
1. 修改web.xml
<context-param>
<param-name>brokerURI</param-name> <param-value>/WEB-INF/activemq.xml</param-value> </context-param> <listener> <listener-class>org.apache.activemq.web.SpringBrokerContextListener</listener-class> </listener>
2. 增加WEB-INF/activemq.xml，如下：
