[rules-users] kContainer.newKieSession() fails in Apache Karaf

[Charles Moulliard]

Hi Joseph,

I propose that you have a look to this example which is currently working
on Karaf - https://github.com/cmoulliard/droolsjbpm-osgi-examples (simple =
OSGI BundleActivator + KieSession + Drools Rules)

Regards,

Charles
