Hi All,
We are using JBpm 5.2 with Spring 3 and Bitronix as transaction manager. JBpm is integrated inside our application, we use the LocalTaskService to create tasks etc. All JBpm relates tables are co-existing with our application.
And another thing is that, we do not use JPA, but rather Hibernate. So there is one datasource, an Entity Manager for JBpm and a SessionFactory for our application. We have configured JTA using Bitronix and spring. Below is the configuration.
{code:xml}
<bean id="transactionManager"
class="com.tarshan.onebill.common.bpm.service.JTATransactionMgr">
<property name="transactionManager" ref="bitronixTransactionManager" />
<property name="userTransaction" ref="bitronixTransactionManager" />
</bean>
<bean id="btmConfig" factory-method="getConfiguration"
class="bitronix.tm.TransactionManagerServices">
<property name="serverId" value="spring-btm" />
<property name="defaultTransactionTimeout" value="300" />
</bean>
<bean id="bitronixTransactionManager" factory-method="getTransactionManager"
class="bitronix.tm.TransactionManagerServices" depends-on="btmConfig"
destroy-method="shutdown">
</bean>
<bean id="jbpmDataSource" class="com.tarshan.onebill.common.bpm.vendor.jbpm.ObPoolingDataSource"
init-method="init" destroy-method="close">
<property name="className" value="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource" />
<property name="uniqueName" value="jdbc/jbpm" />
<property name="minPoolSize" value="1" />
<property name="maxPoolSize" value="3" />
<property name="acquisitionInterval" value="1" />
<property name="acquisitionTimeout" value="15" />
<property name="maxIdleTime" value="15" />
<property name="useTmJoin" value="true" />
<property name="deferConnectionRelease" value="true" />
<property name="automaticEnlistingEnabled" value="true" />
<property name="allowLocalTransactions" value="true" />
<property name="driverProperties" ref="driverProperties" />
</bean>
{code}
Entity Manager configuration:
{code:xml}
<bean id="entityMF2"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" depends-on="btmConfig">
<property name="dataSource" ref="jbpmDataSource" />
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml" />
<property name="loadTimeWeaver">
<bean
class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" />
</property>
<property name="persistenceUnitName" value="org.jbpm.persistence.jpa" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="true" />
</bean>
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.connection.autocommit">false</prop>
<prop key="hibernate.max_fetch_depth">3</prop>
<prop key="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.BTMTransactionManagerLookup
</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.current_session_context_class">jta</prop>
</props>
</property>
</bean>
{code}
Now, we have a service which starts a process and then inserts some records in our application database. If any of the operation fails, JBpm is not rolling back the transaction. The weird thing is that, I could see from the log that Bitronix is rolling back the transaction. I could also see that JBpm is only joining the existing transaction at TaskServiceSession (because we have set transactionType as "local-JTA" while starting the task service).

I am really not clear why the records are still persisted in JBpm tables. Please help me fix this issue. Not sure what I am doing wrong. I could be missing something very basic. Have also uploaded the persistence.xml file.
Thanks for your time.
