I am a Drools newbie, and I think I am having a similar problem with the distribution jars for Drools 5.0.1. I thought there was something missing from my setup...
I originally got a NPE on executing the following line of code: KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); After improving my exception handling, I was able to narrow it down to a "ProviderInitializationException" thrown by the code in the depth of KnowledgeBuilderFactory which was trying to instantiate a missing "provider". Is this the same problem? -------------------------------------------------- David Shields Division of Clinical Informatics Department of Community and Family Medicine Duke University Medical Center Phone (919) 681-6176 Mobile(864) 787-8551 Fax (919) 684-8675 tolitius <[email protected]> Sent by: [email protected] 07/26/2010 02:33 PM Please respond to Rules Users List <[email protected]> To [email protected] cc Subject [rules-users] 5.1.0 CR1: Drools Spring Configuration Changed? JPAKnowledgeServiceBean which is a core entry point into Drools from Spring, used to define/initialize ( in 5.1.0 M2 at least ) a "jpaKnowledgeServiceProvider" ( JPAKnowledgeFactoryService ). Now the initialization is commented out, however "JPAKnowledgeServiceBean" is still trying to use it to create/load Sessions, and of course NullPointerException is raised: https://jira.jboss.org/browse/JBRULES-2593 Any updates were made that depreciate "JPAKnowledgeServiceBean"? Anything different (from 5.1.0 M2) in configuration needs to be done?
