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.

  <bean id="transactionManager"
    <property name="transactionManager" ref="bitronixTransactionManager" />
    <property name="userTransaction" ref="bitronixTransactionManager" />

  <bean id="btmConfig" factory-method="getConfiguration"
    <property name="serverId" value="spring-btm" />
    <property name="defaultTransactionTimeout" value="300" />

  <bean id="bitronixTransactionManager" factory-method="getTransactionManager"
    class="bitronix.tm.TransactionManagerServices" depends-on="btmConfig"

  <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" />

Entity Manager configuration:

  <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">
        class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" />
    <property name="persistenceUnitName" value="org.jbpm.persistence.jpa" />
    <property name="jpaVendorAdapter">
      <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
        <property name="showSql" value="true" />
    <property name="jpaProperties">
        <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 key="hibernate.show_sql">true</prop>
        <prop key="hibernate.current_session_context_class">jta</prop>

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.
