I'm new to web services concept. I have a class where i'm using JBOSS drools api to create a STATEFULKNOWLEDGESESSION. When i try to expose this class as webservices i get an error "NO END POINTS SPECIFIED". 
However if i remove all the methods haveing STATEFULKNOWLEDGESESSION variables as arguments, web service is up and I'm able get the wsdl. Can anyone explain me whats wrong with using statefulknowledgesession inside a webserice. 

Thanks in advance
