Hi
As part of a jBPM4 prototype I'm working on, I would like to add instances of a custom class as process variables. I've created a Hibernate mapping definition and also confirmed that it works as expected when persisting this using the Hibernate API directly. However, when adding my instance as a variable, the following exception is thrown (tested with 4.2 and 4.3):
Exception in thread "main" org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: se.vgregion.rosproto.model.Issue
A reference to the Hibernate mapping has been added to the jBPM Hibernate configuration file (I use the same file when using Hibernate directly).
Do I need to persist the object myself before adding it as a variable or I'm I missing something obivous here? (I'm guessing the latter :-)
Here's the code I'm using, based on jbarrez Hello world example.
          ProcessEngine processEngine = new Configuration().setResource("my.jbpm.cfg.xml").buildProcessEngine();          RepositoryService repositoryService = processEngine.getRepositoryService();          ExecutionService executionService = processEngine.getExecutionService();                    repositoryService.createDeployment().addResourceFromClasspath("hello_world.jpdl.xml").deploy();                    Issue issue = new Issue();          issue.setRequestor("req");          issue.setResponder("resp");                    ProcessInstance instance = executionService.startProcessInstanceByKey("helloWorld");          executionService.setVariable(instance.getId(), "issue", issue);

Hello
I'm having the same problems as Christian stated. We are using JPA transations which worked in version 4.1 and I can't get it running in 4.3 because of the mentioned NPE.
We also have an EntityManager and using the following configurations we provided the connection and transations manager to jBPM:
*jbpm.hibernate.cfg.xml*
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
-//Hibernate/Hibernate Configuration DTD 3.0//EN
http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd>
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">${hibernate.dialect}</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<property name="hibernate.jdbc.batch_size">2000</property>
<property name="javax.persistence.transactionType">JTA</property>
<property name="hibernate.transaction.manager_lookup_class">com.softmodeler.server.persistence.SoftmodelerTransactionManagerLookup</property>
<property name="hibernate.connection.provider_class">com.softmodeler.server.persistence.SoftmodelerConnectionProvider</property>
<mapping resource="jbpm.repository.hbm.xml" />
<mapping resource="jbpm.execution.hbm.xml" />
<mapping resource="jbpm.history.hbm.xml" />
<mapping resource="jbpm.task.hbm.xml" />
<mapping resource="jbpm.identity.hbm.xml" />
</session-factory>
</hibernate-configuration>
Notice the "hibernate.transaction.manager_lookup_class" and the "hibernate.connection.provider_class" properties.
The Spring configuration looked like this, no sessionFactory bean is defined:
<osgi:reference id="transactionManager" interface="org.jencks.GeronimoPlatformTransactionManager"/>
<bean id="jbpmConfiguration" class="org.jbpm.pvm.internal.cfg.SpringConfiguration">
<constructor-arg value="jbpm.cfg.xml"/>
</bean>
<bean id="jbpmProcessEngine" factory-bean="jbpmConfiguration" factory-method="buildProcessEngine"/>
<bean id="jbpmRepositoryService" factory-bean="jbpmProcessEngine" factory-method="getRepositoryService" />
<bean id="jbpmExecutionService" factory-bean="jbpmProcessEngine" factory-method="getExecutionService" />
<bean id="jbpmTaskService" factory-bean="jbpmProcessEngine" factory-method="getTaskService" />
I tried to hack around the code to get it working, made my own SpringProcessEngine without using LocalSessionFactoryBean.
public static ProcessEngine create(ConfigurationImpl configuration) {
MySpringProcessEngine springProcessEngine = null;
ApplicationContext applicationContext = null;
applicationContext = (ApplicationContext) configuration.getApplicationContext();
springProcessEngine = new MySpringProcessEngine();
springProcessEngine.applicationContext = applicationContext;
springProcessEngine.initializeProcessEngine(configuration);
// do not create session, hibernate configuration is set in jbpm.cfg.xml
springProcessEngine.checkDb(configuration);
return springProcessEngine;
}
Well now I'm getting a different NPE, jBPM is trying to access org.springframework.transaction.PlatformTransactionManager, but I'm using org.apache.geronimo.transaction.manager.GeronimoTransactionManager.
What would be the correct way to hock in my TransationManager?
greets and thanks

Hi again!
I finally got it working. I had to change the compiler compliance level to "1.5". Previously I had 1.6 there as it is the default.
Once changing that setting, everything started to work smoothly.
Also upgrading the JBT to CR2 was pretty interesting process I actually started clean from a new eclipse installation as upgrading hit the brick wall every time.. Well I'm kinda new to eclipse so it's my fault
But now my environment is up and running and I can get back to evaluating this great piece of software!
Thanks for your help and keep up the good work!
