[jboss-jira] [JBoss JIRA] Updated: (JBRULES-2604) New simple JPAKnowledgeServiceBean that can be used to create / reload Stateful Knowledge Sessions

New simple JPAKnowledgeServiceBean that can be used to create / reload Stateful Knowledge Sessions -------------------------------------------------------------------------------------------------- Key: JBRULES-2604 URL: https://jira.jboss.org/browse/JBRULES-2604 Project: Drools Issue Type: Patch Security Level: Public(Everyone can see) Components: All Affects Versions: 5.1.0.FINAL Environment: N/A Reporter: Anatoly Polinsky Assignee: Mark Proctor Attachments: JPAKnowledgeServiceBean.java Original Estimate: 1 hour Remaining Estimate: 1 hour Spring bean that serves as a facade into Drools Session creation and reloading using persistent (JPA) knowledge state. Public client APIs are newStatefulKnowledgeSession( ) and loadStatefulKnowledgeSession( sessionID ) which do just that: newStatefulKnowledgeSession(): Creates a new StatefulKnowledgeSession loadStatefulKnowledgeSession( sessionID ): Reloads an existing ( previously persisted StatefulKnowledgeSession ) by the sesssionID Here is an example on how this bean can be configured: <bean id="abstractKnowledgeProvider" class="org.drools.container.spring.beans.persistence.JPAKnowledgeServiceBean"> <property name="entityManagerFactory" ref="entityManagerFactory" /> <property name="transactionManager" ref="txManager" /> <property name="knowledgeStore" ref="kstore"/> <property name="kbase"> <drools:kbase id="kbase" node="node"> <drools:resources> <drools:resource type="DRF" source="classpath:./META-INF/flow/subprocess-flow.rf" /> <drools:resource type="DRF" source="classpath:./META-INF/flow/parallel-subprocess-flow.rf" /> <drools:resource type="DRF" source="classpath:./META-INF/flow/approval-flow.rf" /> </drools:resources> </drools:kbase> </property> <property name="variablePersisters"> <util:map> <entry key="javax.persistence.Entity" value="org.drools.persistence.processinstance.persisters.JPAVariablePersister" /> <entry key="java.io.Serializable" value="org.drools.persistence.processinstance.persisters.SerializableVariablePersister" /> <entry key="java.lang.String" value="org.drools.persistence.processinstance.persisters.StringVariablePersister" /> </util:map> </property> </bean> Besides "variablePersisters" all properties are mandatory ( cannot be NULL / not set ).
