    JBPM 5 DOESN'T WORK

    Thong Huynh Newbie

      Hi people,

      Maybe the title is a little bit subjective but me and my team is getting very frustrated at jBPM 5.

       

      Our problem: user task does not show up after the preceding user task is finished.

       

      What we did:

      - We downloaded the jbpm-5.3.0.Final installer from Jboss community download site (http://sourceforge.net/projects/jbpm/files/jBPM%205/)

      - We unzipped the file and followed the instruction from jbpm 5 user guide (http://docs.jboss.org/jbpm/v5.3/userguide/ch.installer.html#d0e389) to install its components: jboss AS, Eclipse, Drools-Guvnor, JBPM Console, JBPM Eclipse Plugin, Drools Eclipse Plugin

        - We used the component Drools-Guvnor to start modelling a basic process. The steps are as follows:

                + Went to Guvnor with url: http://localhost:8080/drools-guvnor

                + Created a new package in knowledge base

                + Created a new BPMN2 process in the package

                + Modelled a simple process with: Start Event -> User Task 1 -> User Task 2 -> End Event

                + Entered taskname for 2 user tasks and specified actorId as 'krisv' for both of them

                + Generated forms using autogenerated form feature built in (3 forms are generated: 1 processtask form, usertask1 form, usertask2 form)

                + Saved it and built it

      - We went to JBPM Console (http://localhost:8080/jbpm-console) to start reviewing the process.

                + Started the process, the 1st form (processtask form) appears, click submit

                 + Went to Tasks to view the 1st task assigned to krisv (as specified)

                + The task showed up, viewed usertask1 form and confirmed it is as expected

                 + Refreshed the task list and expected to see the next one shows up

                 + NOTHING SHOWS UP

       

      We can also reproduce this problem with the Evaluation sample comes along with the installer. Has anyone encountered this problem and knows exactly what causes it? Any answer would be hightly appreciated.

       

      Cheers

          Can you take a look at the server logs? you will usually find the problem there.

          inside jboss - > /standalone/logs/server.log

           

          Cheers

            Hi Salaboy,

            Thank you very much for your answer. It's a shame that I haven't looked into the log much. I found an error in there which basically says it tries to get a task by workItemId but it couldn't. Here is the log:

             

            Do you have any idea why this error happens? Thanks for your help again.
