问题描述
我正在尝试访问注册为 JBoss v4.2 的MBean
I'm trying to access the JBoss v4.2 MBean registered as
jboss.web:type=Manager,path=/,host=localhost
使用以下代码:
ObjectName name = new ObjectName("jboss.web:type=Manager,path=/,host=localhost");
ManagementFactory.getPlatformMBeanServer().getAttribute(name, "activeSessions");
但是此代码不断引发以下异常:
But this code keeps throwing the following exception:
javax.management.InstanceNotFoundException : jboss.web:type=Manager,path=/,host=localhost is not registered.
另一方面，我可以通过...//localhost:8080/jmx-console/在jmx-console上查看和使用此bean-MBean可用.
On the other hand I'm able to see and use this bean using the jmx-console via ...//localhost:8080/jmx-console/ - the MBean is available.
通过代码访问同一MBean还需要什么?
What else is necessary to access the same MBean via code?
推荐答案
找到了...
ObjectName name = new ObjectName("jboss.web:type=Manager,path=/,host=localhost");
this.sessions = new Long((Integer) MBeanServerLocator.locateJBoss().getAttribute(name, "activeSessions"));
我必须找到正确的MBeanServer ... MBeanServerLocator.locateJBoss()解决了它.
I had to find the right MBeanServer... MBeanServerLocator.locateJBoss() solves it.
