Hi Charles,

Ok it seems that this class is bothering JPA: https://github.com/droolsjbpm/jbpm/blob/master/jbpm-audit/src/main/java/org/jbpm/process/audit/VariableInstanceLog.java#L40

But the weird thing is that all the Entities from jbpm-audit are almost the same. 

Which version of OpenJPA are you using? We should check if they support the: @SequenceGenerator annotation.

I'm sure that if we remove that we will have troubles with some vendors (if I don't remember wrong with Oracle) that require an external table to generate auto incremental values.

Cheers

Here is the error that I have using OpenJPA -->

Question : I try to configure jbpm + HumanTaskManager using OpenJPA instead of Hibernate but gets this error 

Caused by: <openjpa-2.2.1-r422266:1396819 fatal user error> org.apache.openjpa.persistence.ArgumentException: "org.jbpm.process.audit.VariableInstanceLog.id" declares generator name "variableInstanceLogIdSeq", but uses the AUTO generation type.  The only valid generator names under AUTO are "uuid-hex" and "uuid-string".

Hi Charles,

Let us know what problems are you having with the human tasks modules we can help you.

Hi Marco,

Thanks for the response. What you tell me corresponds to what I have packaged and deployed on Karaf 

    <bundle>mvn:org.jbpm/jbpm-audit/${drools.version}</bundle>

    <bundle>mvn:org.jbpm/jbpm-shared-services/${drools.version}</bundle>

    <bundle>mvn:org.jbpm/jbpm-runtime-manager/${drools.version}</bundle>

    <bundle>mvn:org.jbpm/jbpm-human-task-core/${drools.version}</bundle>

    <bundle>mvn:org.jbpm/jbpm-human-task-workitems/${drools.version}</bundle>

    <bundle>mvn:org.jbpm/jbpm-persistence-jpa/${drools.version}</bundle>

I still have some issues with Hibernate or OpenJPA when they reads the model needed by human-task. Will try to have a look next week on that.

Regards,

Charles

Hi Charles,

Re: jars:

• I would look at also adding jbpm-persistence-jpa. Most users like having persistence as well.
• There are also the human-task jars, but I'm not sure which ones are being used now: @Mauricio?
• jbpm-audit (in 5.x: jbpm-bam) is important for logging. 
• jbpm-runtime (started in 6.x) is an important jar if users end up building their own "execution servers", but I think most users will use the execution/console wars available.
  

With regards to the bpmn2 files, you've covered most of the important things:
1. evaluation: basic bpmn2 + human task
2. ruleTask: rule integration

Those examples are representative: there are a couple of other minor edge cases like timers, multi-instance, and event signals/passing, but if the above work (evaluation, ruleTask), then the rest should definitely work as well.


Thanks,
Marco

Hi,

I have been able to run successfully some BPMN2 examples (of the maven project jbpm-examples) --> BPMN2-EvaluationProcess.bpmn2, BPMN2-RuleTask.bpmn2, BPMN2-RuleTask.drl on Apache Karaf (OSGI runtime). 

- Are those examples representative about what we can do with jbpm ?

- Until now, I have deployed the following jars/bundles : jbpm-flow-builder, jbpm-flow & jbpm-bpmn2 on Karaf. Do I have to deploy something else ?

Regards,
