[rules-users] IllegalStateException : DroolsJPAManager while calling session.dispose() method.

[drooRam]

i am facing the above problem when i tried to integrate hibernate with
drools.....

Anyone used hibernate with drools? If so, what is the transaction manager
setting for hibernate + drools + tomcat.... i am trying to use the default
transaction manager or the jpa transaction manager implementation from
spring....like the one below... but running into the above error....
