jbpm 5.4 Spring

Spring using the JTA transaction manager

The following code sample shows the Spring configuration file, configured for JTA transactions (using Bitronix in this case) with a shared entity manager factory (emf).

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"        xmlns:jbpm="http://drools.org/schema/drools-spring"        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd                            http://drools.org/schema/drools-spring http://drools.org/schema/drools-spring-1.3.0.xsd">    <bean id="jbpmEMF" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">     <property name="persistenceUnitName" value="org.jbpm.persistence.jta"/>   </bean>    <bean id="btmConfig" factory-method="getConfiguration" class="bitronix.tm.TransactionManagerServices">   </bean>    <bean id="BitronixTransactionManager" factory-method="getTransactionManager"         class="bitronix.tm.TransactionManagerServices" depends-on="btmConfig" destroy-method="shutdown" />      <bean id="jbpmTxManager" class="org.springframework.transaction.jta.JtaTransactionManager">     <property name="transactionManager" ref="BitronixTransactionManager" />     <property name="userTransaction" ref="BitronixTransactionManager" />   </bean>      <jbpm:kbase id="kbase1">     <jbpm:resources>       <jbpm:resource type="BPMN2" source="classpath:MyProcess.bpmn"/>     </jbpm:resources>   </jbpm:kbase>    <jbpm:ksession id="ksession1" type="stateful" kbase="kbase1">     <jbpm:configuration>       <jbpm:jpa-persistence>         <jbpm:transaction-manager ref="txManager"/>         <jbpm:entity-manager-factory ref="emf"/>       </jbpm:jpa-persistence>     </jbpm:configuration>   </jbpm:ksession>

And the matching persistence.xml file:

 <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"              xsi:schemaLocation="http://java.sun.com/xml/ns/persistence                                  http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">    <persistence-unit name="org.jbpm.persistence.jta" transaction-type="JTA">     <provider>org.hibernate.ejb.HibernatePersistence</provider>     <jta-data-source>jdbc/jbpm-ds</jta-data-source>      <!-- Use this if you are using JPA1 / Hibernate3 -->      <mapping-file>META-INF/JBPMorm.xml</mapping-file>     <mapping-file>META-INF/ProcessInstanceInfo.hbm.xml</mapping-file>     <!-- Use this if you are using JPA2 / Hibernate4 -->      <!--mapping-file>META-INF/JBPMorm-JPA2.xml</mapping-file-->      <class>org.drools.persistence.info.SessionInfo</class>     <class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class>     <class>org.drools.persistence.info.WorkItemInfo</class>      <class>org.jbpm.process.audit.ProcessInstanceLog</class>     <class>org.jbpm.process.audit.NodeInstanceLog</class>     <class>org.jbpm.process.audit.VariableInstanceLog</class>          <properties>       <property name="hibernate.max_fetch_depth" value="3"/>       <property name="hibernate.hbm2ddl.auto" value="update"/>       <property name="hibernate.show_sql" value="false"/>       <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>       <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.BTMTransactionManagerLookup" />     </properties>   </persistence-unit> </persistence>
