[jboss-jira] [JBoss JIRA] Created: (JBRULES-2593) JPAKnowledgeServiceBean does not initialize JPAKnowledgeFactoryService

[Anatoly Polinsky (JIRA)]

JPAKnowledgeServiceBean does not initialize JPAKnowledgeFactoryService
----------------------------------------------------------------------

                 Key: JBRULES-2593
                 URL: https://jira.jboss.org/browse/JBRULES-2593
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: All
    Affects Versions: 5.1.0.CR1
         Environment: N/A
            Reporter: Anatoly Polinsky
            Assignee: Mark Proctor


private JPAKnowledgeFactoryService                           jpaKnowledgeServiceProvider;

in "JPAKnowledgeServiceBean" is not initialized. It used to be by:

    protected void initDao() {

        ...  ...  ...

        jpaKnowledgeServiceProvider = node.get( JPAKnowledgeFactoryService.class );
        if ( jpaKnowledgeServiceProvider instanceof JPAKnowledgeProviderLocalClient ) {
            JPAKnowledgeProviderLocalClient local = (JPAKnowledgeProviderLocalClient) jpaKnowledgeServiceProvider;
            local.setCommandServiceClass( SpringSingleSessionCommandService.class );
        } else {
            throw new RuntimeDroolsException( "JPAKnowledgeService is not instance of: " + JPAKnowledgeProviderLocalClient.class.getName() );
        }
    }

but now this code is commented out [ in the latest SNAPSHOT as well ]. Therefore both:

    public StatefulKnowledgeSession newStatefulKnowledgeSession() {}

and

    public StatefulKnowledgeSession loadStatefulKnowledgeSession(final int sessionId) {}

FAIL, since they use jpaKnowledgeServiceProvider to create / load Sessions:

         return jpaKnowledgeServiceProvider.newStatefulKnowledgeSession..
         return jpaKnowledgeServiceProvider.loadStatefulKnowledgeSession..

-------------------------------------------------------------------------------------------------------------------

I understand "SpringSingleSessionCommandService" was removed, but this is not the reason to document the whole thing as it breaks the code base that depends on it.

-------------------------------------------------------------------------------------------------------------------

If "JPAKnowledgeServiceBean" is deprecated, or a different configuration required, please advise. Is it documented?


Thank you,
