Hi,
I've strange problem with spring and jbpm. I have code which works sth like that:
Session session = sessionFactory.getCurrentSession();
Order order = new Order();
ExecutionImpl e = processEngine.startProcess(order);
log(e.getId()); //this logs new process id from jbpm4_execution table, let's say id
= 1000
order.setProcess(e);
session.save(order);
order entity has a foreign key to the process it's connected to.
on saving order in last line I have error from DB the process with id = 1000 does not
exist.
I debug jbpm and dig into RepositorySessionImpl - it has hibernate session object
encapsulated and it's different than 'my' session object.
But they both have the same SessionFactory object (the same hashcode etc).
My spring context xml looks like that (fragment)
<bean id="sessionFactory" autowire="default"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<props>

</bean>
<bean id="dataSource"

<bean id="springHelper"

</property>
</bean>
<bean id="processEngine" factory-bean="springHelper"
factory-method="createProcessEngine" />
<bean id="repositoryService" factory-bean="processEngine"
factory-method="getRepositoryService" />
<bean id="executionService" factory-bean="processEngine"

<bean id="processEngine" factory-bean="springHelper"

<bean id="repositoryService" factory-bean="processEngine"

<bean id="taskService" factory-bean="processEngine"
factory-method="getTaskService" />
<bean id="historyService" factory-bean="processEngine"
factory-method="getHistoryService" />
<bean id="managementService" factory-bean="processEngine"
factory-method="getManagementService" />
and jbpm.cfg.xml looks like that:
<jbpm-configuration>
<import resource="jbpm.default.cfg.xml" />
<import resource="jbpm.businesscalendar.cfg.xml" />
<import resource="jbpm.tx.hibernate.cfg.xml" />
<import resource="jbpm.jpdl.cfg.xml" />
<!-- <import resource="jbpm.bpmn.cfg.xml" />-->
<import resource="jbpm.identity.cfg.xml" />
<!-- Job executor is excluded for running the example test cases. -->
<!-- To enable timers and messages in production use, this should be included.
-->
<!--
<import resource="jbpm.jobexecutor.cfg.xml" />
-->
<process-engine-context>
<command-service name="newTxRequiredCommandService">
<retry-interceptor />
<environment-interceptor policy="requiresNew" />
<spring-transaction-interceptor
policy="requiresNew" />
</command-service>
<command-service name="txRequiredCommandService">
<retry-interceptor />
<environment-interceptor />
<spring-transaction-interceptor />
</command-service>
</process-engine-context>
<transaction-context>
<transaction type="spring" />
<hibernate-session current="true" />
</transaction-context>
</jbpm-configuration>
Where's my mistake? It looks there is no shared transaction between my code and jbpm
code. All methods are marked @Transactional in my code, and stack trace shows tx
interceptors is up and running. But I still don't know why I have 2 different sessions
and 1 common sessionfactory.
any help would be appreciated :)
regards
mk
