I was trying to configure persistence in other way, using Bitronix. My spring-conf.xml file is:
<bean id="transactionManager"
class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="transactionManager" ref="bitronixTransactionManager" />
<property name="userTransaction" ref="bitronixTransactionManager" />
</bean>
<bean id="bitronixTransactionManager" factory-method="getTransactionManager"
class="bitronix.tm.TransactionManagerServices" depends-on="transactionManager"
destroy-method="shutdown" />
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="oracle" />
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="databasePlatform" value="org.hibernate.dialect.Oracle10gDialect" />
<property name="showSql" value="true" />
<property name="generateDdl" value="false" />
</bean>
</property>
</bean>
<jbpm:kbase id="kbase">
<jbpm:resources>
<jbpm:resource type="BPMN2" source="classpath:Hi.bpmn" />
</jbpm:resources>
</jbpm:kbase>
<jbpm:ksession id="persistentKSession" type="stateful"
kbase="kbase">
<jbpm:configuration>
<jbpm:jpa-persistence>
<jbpm:transaction-manager ref="transactionManager" />
<jbpm:entity-manager-factory ref="entityManagerFactory" />
</jbpm:jpa-persistence>
</jbpm:configuration>
</jbpm:ksession>
And persistence.xml file is:
<persistence-unit name="oracle" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source></jta-data-source>
<mapping-file>META-INF/JBPMorm.xml</mapping-file>
<class>org.drools.persistence.info.SessionInfo</class>
<class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class>
<class>org.drools.persistence.info.WorkItemInfo</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
<property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/>
<property name="hibernate.connection.url" value="jdbc:oracle:thin:@localhost:1521:xe" />
<property name="hibernate.connection.username" value="apsfsample"/>
<property name="hibernate.connection.password" value="apsf"/>
<property name="hibernate.connection.autocommit" value="false" />
<property name="hibernate.max_fetch_depth" value="3"/>
<property name="hibernate.hbm2ddl.auto" value="create" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.BTMTransactionManagerLookup"/>
</properties>
</persistence-unit>
</persistence>
I steel got an exeption. It seems that the session can be commited in database. The error is:
