Hello Everyone,
I have requirement where i need to show tracking of an workflow. However history for task, Activity, Process intances are saved into corresponding history tables.
But while browsing through JBPM4_HIST_VAR table , i am unable to get ani information about process variables.
please see the following code.
ProcessInstance pInstance =
executionService
Map<String, Object> params = new HashMap<String, Object>();
params.put("SubmittalCoordinator", "HO-DWG");
params.put("CivilDepartment", "HO-CIVIL");
params.put("MechanicalDepartment", "HO-MECH");
ProcessInstance pInstance = executionService.startProcessInstanceByKey("workflowStatus", params);
executionService.setVariable(pInstance.getId(), "ProcessInstanceId", "workflowStatus");
repositoryService.createDeployment().addResourceFromClasspath("insight/abg/jbpm/workflowStatus.jpdl.xml").setName("workflowStatus").deploy();
ProcessInstance pInstance = executionService
.startProcessInstanceByKey(instanceKey, params);
executionService.setVariable(pInstance.getId(), "ProcessInstanceId", pInstance);
((ExecutionImpl)pInstance).createVariable("someString", "SomeString","string",true);
Variable variable = ((ExecutionImpl)pInstance).getVariableObject( "SomeString");
HistoryEvent.fire(new VariableCreate(variable));
// EnvironmentImpl environment = ((EnvironmentFactory) processEngine).openEnvironment();
// try {
// ((ExecutionImpl)pInstance).createVariable("someString", "SomeString","string",true);
// Session session = environment.get(Session.class);
// Transaction tx = session.beginTransaction();
// session.update(pInstance);
// tx.commit();
// } finally {
// environment.close();
// }
While debugging I am able to see data in variable object, but it is not getting save in JBPM4_HIST_VAR table.
Can anyone help me?
Thanks in advance .
Regards,
Santosh

[jBPM] - last_read_date update causing StaleObjectStateException

"last_read_date update causing StaleObjectStateException"

Hello there,
*jbpm 5.3.0.Final*
I have a server running jbpm happily on a couple of load-balanced hosts. All fine until I use a simple Web interface to view details of a running peocess. This UI calls kSession.getProcessInstance(id) to access process variables. The server handling that process promptly gets a hibernate StaleObjectStateException. The immediate cause seems to be that getProcessInstance generates an update to process_instance_info.last_read_date. The server falls over when attempting update a process following an event.
What I am attempting to do seems reasonable - providing a readonly view to an in-flight process. Is there something flawed in my approach? If I removed the call to updateLastReadDate() in JPAProcessInstanceManager would there be any repercussions other than an inaccurate value in the field?
Thanks for any help.
Richard

Hi,
I am trying to configure jBPM 5.3 persistence configured and having troubles, any help will be gretaly appreciated. So here is what I am doing :
My use case involves building a JEE6 web app with jBPM 5.2 engine embedded in it.
I am using JBoss Developer Studio 5.0 Beta 3 to generate a JEE6 web app using one of the maven plugins. Once the app is generated, I have added dependencies on jbpm-bpmn2 and jbpm-persistence-jpa. I have also updated the persistence.xml file (please see the attached file). Note that I have 2 persistence units in it : one for application data and other for jbpm. When I deploy this application to AS 7.1.0, (mvn clean package jboss-as:deploy), I get the following persistence exception :
=========================================================================================================================================
