--------------------------------------------------------------
Hey guys,
I have been trying to integrate JBPM6 in my Spring-Hibernate based Grails application, but
it seems that I'm stuck and maybe you guys here could point me in the right
direction.
I am trying to get the RuntimeManager working with a local spring transaction scheme. I
have tried a lot of stuff but can't seem to find the right approach.
I have set up a EntityManagerFactory bean, which loads the persistence-unit
org.jbpm.presistence.jpa (with transaction-type "Resource_local") with the
org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter.
I have also set up a org.springframework.orm.jpa.JpaTransactionManager bean.
When I now try to get a runtimeEngine via the RuntimeEnvironmentBuilder:
RuntimeEnvironment environment = RuntimeEnvironmentBuilder.getDefaultInMemory()
.userGroupCallback(getUserGroupCallback())
.entityManagerFactory(entityManagerFactory)
.registerableItemsFactory(new
KModuleRegisterableItemsFactory(kcontainer,''))
.addEnvironmentEntry(EnvironmentName.TRANSACTION_MANAGER,jbpmTransactionManager)
.get();
RuntimeManager manager =
RuntimeManagerFactory.Factory.get().newPerProcessInstanceRuntimeManager(environment);
RuntimeEngine runtime = manager.getRuntimeEngine(ProcessInstanceIdContext.get());
I get the following error:
NamingException occurred when processing request: [GET] /bpm/test/
Cannot create resource instance. Stacktrace follows:

Looking at the stacktrace I found the the LocalTaskServiceFactory where the documentation
says:
/**
* Regular <code>TaskServiceFactory</code> implementation that shall be used
for non CDI environments.
* Creates new <code>TaskService</code> instance for every call to the
factory.
* <code>TaskService</code> instance will be equipped with
<code>JbpmJTATransactionManager</code>
* for transaction management, this is mandatory as it must participate in already active
* transaction if such exists.
*/
So it seems it's not possible to use the RuntimeManager without a JTA Transaction
Manager? I thought it might be possible to supply the localTransactionManager via the
Environment? But I am fishing in the dark.
If I am totally off the mark here in what I am doing, I would appreciate any pointer into
the recommended way to integrate jbpm6 (and especially the runtime manager) into a
spring-hibernate based application. I have looked at kie-spring, but there is little jbpm
specific stuff.
Cheers, Alex
