[rules-users] Drools 5.1 Persistence without JTA

[tolitius]

yea, for the process ( flow ) it seems to work fine using a regular
"org.springframework.orm.jpa.JpaTransactionManager":

	<bean id="abstractKnowledgeProvider"
	     
class="org.drools.container.spring.beans.persistence.JPAKnowledgeServiceBean"
	      abstract="true">

	      <property name="entityManagerFactory" ref="entityManagerFactory" />
	      <property name="transactionManager" ref="txManager" />
	      <property name="variablePersisters">
			<util:map>
				<entry key="javax.persistence.Entity"
				
value="org.drools.persistence.processinstance.persisters.JPAVariablePersister"
/>
				<entry key="java.lang.String"
				
value="com.jpmc.tss.admincenter.framework.workflow.drools.variablepersistence.StringVariablePersister"
/>
				<entry key="java.io.Serializable"
				
value="org.drools.persistence.processinstance.persisters.SerializableVariablePersister"
/>
			</util:map>
	       </property>
	</bean>

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

	<bean id="entityManagerFactory"
	
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
		<property name="persistenceUnitName" value="your.persistence.unit" />
		<property name="dataSource" ref="datasource" />
		<property name="jpaProperties">
			<props>
                <prop
key="hibernate.connection.autocommit">${hibernate.connection.autocommit}</prop>
                <prop
key="hibernate.max_fetch_depth">${hibernate.max_fetch_depth}</prop>
                <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
	            <prop key="hibernate.dialect">${hibernate.dialect}</prop>
	            <prop
key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
			</props>
		</property>
	</bean>

	<bean
class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"
/>
	<bean
class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>

	<drools:connection id="connection1" type="local" />
	<drools:execution-node id="node1" connection="connection1" />
