      I have in my beans.xml

      <drools:ksession id="jpaSingleSessionCommandService" type="stateful" kbase="kbase" >

        <drools:configuration>

        <drools:jpa-persistence>

        <drools:transaction-manager ref="jpaTxManager" />

        <drools:entity-manager-factory ref="myEmf" />

        </drools:jpa-persistence>

        </drools:configuration>

      </drools:ksession>                                                                                               

      and I get these error message

      I'm using drools 5.4.0 and jbpm 5.3.0.

      I'd checked the drools-core-5.4.0.Final.jar and org.drools.command.Context is no longer there.

      Any idea?
