      Hi Team,

             I am working on jBPM 5.2. Is there any workflow(API) to retrieve data from table of jBPM internal database(H2)?.When will you release jBPM5 book?.

       

       

       

      Regards,

          If you want to get the data of

           

          • ProcessInstances , Session details  -  Use the methods in the object of knowledgeSession you have created (org.drools.runtime.StatefulKnowledgeSession)
          • Tasks - Use the methods in the task client object connected to the task server (org.jbpm.task.service.TaskClient)
          • ProcessInstanceLog,NodeInstanceLog,VariableInstanceLog - Use the methods in JPAProcessInstanceDbLog object create after enabling the JPAWorkingMemoryDbLogger (org.jbpm.process.audit.JPAProcessInstanceDbLog)

           

          Check the code attached to   https://community.jboss.org/people/bpmn2user/blog/2011/09/21/jbpm5-web-example  for how to create Session , task client

           

          For creating JPAProcessInstanceDbLog object refer the below code

           

           

          //Enabling the history Service 
JPAWorkingMemoryDbLogger workingMemoryDbLogger =  new JPAWorkingMemoryDbLogger(knowledgeSession);
// Get the JPA interface for History service 
JPAProcessInstanceDbLog historyService = new JPAProcessInstanceDbLog(knowledgeSession.getEnvironment());

           

           

          Cheers
