Gathering the information of a Queue in Java

In the JMX Console when we click on a queue name link say
"BrokerName=localhost,Destination=dlq.queue,Type=Queue" 
we will get a page (which lists Queue size, EnqueueCount, DequeueCount etc)   
which describes the JMX MbeanView of the queue(ie dlq.queue) which we have
selected.

I need to get the same info in my java code.Is it possible?

Scenario is like this:
I have an instance of BrokerService with me.
I tried checking in the BrokerService and BrokerView (obtained as
brokerService.getAdminView())
but unable to find any suitable placeholders for getting a specific queue
information.
Tried invoking getDestinations() on the broker instance.It returned a list
of ActiveMQDestinations.
But that also doesnt have the MBean attributes which i need to check for a
specific Queue.
Please help me.

Thanks
Aneesh

I went through those, but still cant get it..

I only have the BrokerService instance with me.
>From this instance i need to look up the attributes of a queue..
is it possible?

Basically from the junit files in the repository this is the way in whic we
can get a QueueViewMbean instance of a queue;

 ObjectName queueViewMBeanName = assertRegisteredObjectName(domain +
":Type=Queue,Destination=" + getDestinationString() +
",BrokerName=localhost");

 QueueViewMBean queue =
(QueueViewMBean)MBeanServerInvocationHandler.newProxyInstance(mbeanServer,
queueViewMBeanName, QueueViewMBean.class, true);

 
How can i obtain this from the BrokerService instance?
I cant get the MBeanServer from the BrokerService
Any suggestions will be really helpful..

Thanks

There are a lot of examples on how to get broker data using JMX in unit
tests. Take a look at this one for example
