Durable consumers

Hi,

Currently I was using SonicMQ. In that if there is any durable consumer for a Topic, it was not necessary that messages should be persistent. SonicMQ itself sees, if there is any durable consumers for a Topic, it stores the messages until it delievers the messages to all of its durable consumers.

But in OpenJMS , durable consumers of a Topic receives messages only if messages sent on that Topic are persistent. Is it OK, or I am doing something wrong.

Thanks!
Sanjeev
