Thanks for the response


I am using JPAKnowledgeService, initialized from Spring application context configuration file:
          <jbpm:kbase id="kbase">
                    <jbpm:resources>
                              <jbpm:resource type="BPMN2" source="classpath:workflows/Test.bpmn" />
                    </jbpm:resources>
          </jbpm:kbase>
          <jbpm:ksession id="ksession" type="stateful" kbase="kbase">
                    <jbpm:configuration>
                              <jbpm:jpa-persistence>
                                        <jbpm:entity-manager-factory ref="entityManagerFactory"/>
                                        <jbpm:transaction-manager ref="transactionManager"/>
                              </jbpm:jpa-persistence>
                    </jbpm:configuration>
          </jbpm:ksession>


CommandBasedWSHumanTaskHandler is configured to execute connect method at application startup.
And for completing a task the code just execute the task client method:
          BlockingTaskOperationResponseHandler completeResponseHandler = new BlockingTaskOperationResponseHandler();
          getTaskClient().complete(taskId, userId, null, completeResponseHandler);
          completeResponseHandler.waitTillDone(getClientMaxWaitTime());


The session is loaded, because I previously can create process instances, and the task client can change task status to Completed.


Should I do something more? What listener must I declare?
The CommandBasedWSHumanTaskHandler.connect works fine, but when TaskCompletedHandler executes the PersistenceContext stored in the session environment has a reference to a closed EntityManager.
