We are using a Tibco EMS Queue to send messages. We are the publisher. Whenever we are publishing messages it seems someone is consuming that. When we asked the other team who is subscribing, they said they are not consuming.

Is it possible to know to who is connected to the EMS Queue and consuming the messages?

If you've got access to the EMS dashboard utility then bring up the view of all queues on the server, then right-click on the queue you're interested in and select "Consumers" and it will give you a detailed view of who is attached to a queue.

If you don't have the dashboard app then you'll probably need to hassle your EMS admins for a copy. It's part of the standard install, so they will have it.

You could very well use the tools that come with TIBCO EMS. There is also a very good tool called "Gems" which gives you a power-user like control over EMS. I usually prefer Gems when I have to do some monitoring (something like your case)

Heres a tutorial for Gems. http://www.youtube.com/watch?v=GvRN1auqXvE

You can use TibjmsAdmin.getConsumers() as in to get all consumer information. Even from a queue. Shouldn't you use topics instead of queues if you have multiple consumers ?

public ConsumerInfo[] getConsumers(java.lang.Long connectionID, java.lang.String username, DestinationInfo destination, boolean durable, int dataFlags) throws TibjmsAdminException

Queues are meant for the point to point communications. Officially there should be only one subscriber, you can do show queue and find out the number of subscribers to the queue.
