Hello there,

JBPM 5.1 on Tomcat, persistence configured in Spring

I have a number of processes, each with a series of service tasks punctuated by timers.

I would like to persist process data after every service task to be confident that it is recoverable on catastrophic failure. I find, though, that data is committed only at timers and end of process. Is it possible to take control of transactions at a more granular level to get jbpm to commit more regularly?


My config.. 

<bean class="org.springframework.orm.jpa.JpaTransactionManager"
    id="transactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

<tx:annotation-driven mode="aspectj"
    transaction-manager="transactionManager" />

<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    id="entityManagerFactory">
    <property name="persistenceUnitName" value="persistenceUnit" />
    <property name="dataSource" ref="dataSource" />
</bean>

<bean class="org.springframework.orm.jpa.JpaTransactionManager"
    id="transactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

<drools:jpa-persistence>
    <drools:transaction-manager ref="transactionManager" />
    <drools:entity-manager-factory ref="entityManagerFactory" />   
</drools:jpa-persistence>


Thanks,
Richard
