Unable to create TopicSubscriber

I am using the JMS sample provided on the Advantage site. While trying to create the Topic Subscriber i am getiing the following error

“Unable to create TopicSubscriber: Unknown Document Type (226-1490): Document type ‘Broker::JMS::DefaultEvent’ is not defined in the Broker.”

What does it try to imply and what is the probable solution to the same

Hi Gautam,

sounds like an installation issue:

Did you install the JMS Provider along with the Broker?
