I am using JMS and have used TopicRequester to publish a topic. Is there any way of knowing how many subscribers are there to the topic?
Please help

Not programatically (easily) ... but the latest release of MQJExplorer now contains Pub/Sub interrogation via a GUI ... you can see a list and details of each subscriber by topic.

Hi,

I am using the Integrator for Pub/Sub.
To count the subscribers I ammended the subscribe flow to generate the RFH2 header with a counter for each topic which is incremented and saved in a database. The unsubscribe flow will do the opposit. But this method does not work if the subscriber crashes.
