- Lookup Singleton MBean 2007-06-11 - By niefeng
Back
Hi all,
I followed the configuration as specified on the OnJava.com (http://www.onjava
.com/pub/a/onjava/2003/08/20/jboss_clustering.html) to configure a singleton
MBean within the cluster env.
However, i have problem on locating the singleton MBean. Below is my excerpt of
my code on getting the mbean.
| String mbeanName = mbeanName = getServiceMBeanName();
| MBeanServer server = MBeanServerLocator.locate();
| AServiceMBean mbean = (AServiceMBean)MBeanProxyExt.create(AServiceMBean
.class, mbeanName, server);
| System.out.println("is Master node: "+mbean.isMasterNode());
|
The isMasterNode status will be true if the mbean is started as the singleton.
On node 1, i tried to run the code and the above code stated it is a master
node. On node 2, i tried the same thing, but i can't locate the singleton MBean
cos the status i get is showng false.
Seem like the MBean i am getting is from the Node2 MBeanServer instead of the
Node1 mbean server.
Is the way i perform the look up wrongly?
Many thanks
