I saw the different variable persistence strategies provided by drools in 5.1.1 (
http://planet.jboss.org/post/drools_flow_variable_persistence_strategies
http://planet.jboss.org/post/drools_flow_variable_persistence_strategies). I dont find
those classes anywhere when I downloaded the jBPM5.0.0 installer which comes with
drools-persistence-jpa-5.2.0.M1.jar.
The classes I am looking for are
JPAPersistedVariable.class
VariableInstanceInfo.class
These used to be bundled in drools-persistence-jpa-5.1.1.jar. Does anyone know if I need
some other jar file to get these classes?
Also if you have an example of working variable persistence, please send me a link to it.
Regards
Harjot Narula

Hi Harjot,
In 5.2 we merge the current implementation for Variable Persistence with the core
marshaling mechanisms of drools.
You can find a test that show how to configure the new Persisters in the following test
inside the jbpm-persistence-jpa project:
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-persistence-jpa/src/t...
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-persistence-jpa/src/t...
I was responsible for that merge and for the unification of these mechanisms, so please
feel free to report any problem that you have with it.
Greetings.

Hey Mauricio,
I was wondering if there were any changes to the behavior of calling:
env.set(EnvironmentName.CMD_SCOPED_ENTITY_MANAGER, myCmdScopedEntityManager);
I seem to get the following stack trace when using this (it worked in the previous
release)
SEVERE: [http-thread-pool-8080(2)] ERROR essionCommandService - Could not commit session

i encounter the same exception, you can try un-register the JPAWorkingMemoryDbLogger but
comment the line:
//new JPAWorkingMemoryDbLogger(ksession);

Hmm that error doens't seem related with the variable persistence strategies.. when
