I resolved my problem by using all Spring beans. 

    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="persistenceUnitName" value="com.navis.control.persistence.jpa" />
    </bean>


    <bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
    </bean>

ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("ApplicationContext.xml");
        Environmentenv = KnowledgeBaseFactory.newEnvironment(); 
        env.set(EnvironmentName.ENTITY_MANAGER_FACTORY,applicationContext.getBean("entityManagerFactory"));
        env.set(EnvironmentName.TRANSACTION_MANAGER, applicationContext.getBean("txManager"));
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("aFile"), ResourceType.BPMN2);
kbuilder.add(ResourceFactory.newClassPathResource("aRule"), ResourceType.DRL);
KnowledgeBase kbase = kbuilder.newKnowledgeBase();

StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env);
