I have two queries and pointers/references to them will be a great help to me
*1.) History Information :* I understand that history can be logged by using
JPAWorkingMemoryDbLogger logger = new JPAWorkingMemoryDbLogger(ksession);
and the same is working as required.
*Ques :* How to retreive the information which is logged using API ? Any example. I read
in documentation that it is using the Process Event Listener.
But does it work?
*2.) Reporting :* Reports for the process can be seen in the jBPM console. But I need to
develop mine using APIs
*Ques:* Any reference for the same?
Regards,
Sandeep Sapra

We want to log all activities performed in the process workflow as the Process definition
mostly contains all Human Tasks.
Please help us.

Hi.
You can use
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-bam/src/main/java/org...
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-bam/src/main/java/org...
to get information from audit tables.

Thank you Demian.
But after replacing the line
JPAWorkingMemoryDbLogger jpaLogger = new JPAWorkingMemoryDbLogger(ksession);
with
JPAProcessInstanceDbLog jpaLogger = new JPAProcessInstanceDbLog
(ksession.getEnvironment());
Could not see any significant logging records added in PROCESSINSTANCEINFO and
PROCESSINSTANCELOG.
Could you please let me know the relevant API call to retrive the history details for
perticular workflow executed.

Hi Sandip,
both should be there.
JPAWorkingMemoryDbLogger will register a listener and log in the database.
JPAProcessInstanceDbLog just queries these tables.

Hi Demian,
Sorry for being so dump :(
What could be the wrong with following code. I am getting NPE.
public void init() throws ServletException {
super.init();
try {
UserTransaction ut = (UserTransaction) new
InitialContext().lookup("java:comp/UserTransaction");
ut.begin();
StatefulKnowledgeSession ksession = JbpmAPIUtil.getSession();
/* Create the knowledge base */
JPAWorkingMemoryDbLogger logger = new JPAWorkingMemoryDbLogger (ksession);
JPAProcessInstanceDbLog processInstaceLogger = new JPAProcessInstanceDbLog
(ksession.getEnvironment());
CommandBasedWSHumanTaskHandler taskHandler = new
CommandBasedWSHumanTaskHandler(ksession);
ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
taskHandler);
taskHandler.connect();
ut.commit();
logger.dispose();
processInstaceLogger.dispose();
} catch (Throwable t) {
// log.error(t.getMessage(), t.getCause());
throw new RuntimeException("error while creating session", t);
}
}

It seems to be a bug in dispose method, which is solved in master:
https://github.com/droolsjbpm/jbpm/blob/5.1.0.M1.x/jbpm-bam/src/main/java...
https://github.com/droolsjbpm/jbpm/blob/5.1.0.M1.x/jbpm-bam/src/main/java...
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-bam/src/main/java/org...
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-bam/src/main/java/org...
em is null because you never used it.
Anyway, to use this Process instance Log,
you can just use processInstaceLogger.find<Process/Node/Variable>Instances method to
get the information you need.
