JMS creating topics dynamically

I am developing a webapp using Spring and there are several other apps that are influenced by the information generated in mine. Basically they want to know when a change has been made in the data I manage. This data can be filtered by a certain A property.

Since the number of apps to "subscribe" to this information is variable, I thought about implementing a JMS publisher/subscriber model in which I create queues according to the filtering A property and then notify of changes to that queue. All subscribers would then receive the notification through their JMS listeners.

Is this scenario even possible? That is, can I embed a JMS queue in my Spring webapp (how?) and can I create these queues dynamically (i.e. I create queues for my A catalogue, then if a new element gets added to that catalogue, a new queue should be created dynamically without human intervention). Or is there any better solution to create this filtering functionality?

if i am not mistaken you cannot create dynamic queues as and when you want as you create a fixed set of queues on the server machine in any env which you use in your code. thats one drawback for the above design – vikeng21
then how would you implement such functionality? Is there a way to filter messages in a single JMS queue? – MichelReap
