    Human Task , task table deleted every time, when I restart the jbpm-install demo application..

    Prabakar Singaram Newbie

      Hi,

       

      I try to install jbpm5.3 installer, afer some persistence related fixes, It is working fine.

      but I have one problem, each time when I stop and start the demo.db, all the records in task table get deleted, even though some reserved data is there it deletes all.

       

      please advise me, how to prevent this, below is my task service persistence.xml...........

       

       

      thanks,

          • 3. Re: Human Task , task table deleted every time, when I restart the jbpm-install demo application..
            Prabakar Singaram Newbie

            yes...

            start Jobss 7 AS, human task, etc...using jbpm-console...using command "start.demo.db"

            1 - login as krisv/krisv start the process and complete the task, logout

            2 - login as john/john and complet the task, log out

            3 - log in as mary/mary and complete the task, log out,

            4 - log in as krisv/krisv and start the process and complete the task

             

            data sored in the database,  I saw data in the task table for john and mary is reserved and stiil the data is there, workitem table session table processinfo table all having data for the incomplete process...all working fine as expected,

             

            4.stop the all servicess using "ant stop.demo.db" (jboss, task service)

            5. restart the all the service using "ant start.demo.db"...

            6. login as john/john , but I dont see any task listed in the consolo...

             

            When I check the database , what happen is it delete the data in task table....thats why it is not showing any task for john and mary,

             

            my question is how to prevent this from deleting the data from the task table....

            I suspect hibernate query or persistence.xml modification etc...but I am not sure...2 days breaking my head...no use...

            please provide some tool to dig this problem...

             

            thanks

              You need to find the persistence.xml which is erasing the database.. that's hibernate configuration.

              If you are in linux grep all the files to find all the persistence.xml files around and make sure that all of them are pointing to your mysql.

              You should also take a look at the AS configuration files which can be defining a Data Source which can also be causing that behavior.

              Cheers

                  Is any way, or is it possible to start the servicess  only(server and task service not db file creating)? using the ant sctipt in the build.xml?...I tried but cause lots of other exceptions...I just want to start the service i do not want to disturb the db file (after first time creating)...after that let the application handle this not ant script doing all deleting task...how to achive this

                  thanks,

                    yes, you are right, I updated the persistence.xml files(2 files) in task service folder and 3 files in lib folder(gwt server and task server war files), the problem resolved,

                     

                    jbpm-installer working beautifully as expected...great job JBPM team.

                      I have a questing inmy mind why do we need so many persistence.xml for task service?

                       

                      thanks,
