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?

You can use selectors (by property A) instead of creating queue:

For dynamic queue, see Creating temporary JMS jms topic in Spring
