    Sharing jbpmContext with two different threads on jBPM3

    François-Xavier Seheut de Ronchi Newbie

      Hello everynone. My first post. I think I read every post about the jBpmContext and nothing gave me the solution...

       

      I'm using jBPM 3 with SEAM. I launch an asynchronous event which launches a ProcessInstance.

       

      I am using another asynchronous event to cancel the previously launched ProcessInstance.

       

      @Observer("builderObserver")

          public void startProcessForBuilder(final PackageConfiguration packageConfiguration, final Package pack) {

              try {

                  final JbpmConfiguration jbpmConfig = JbpmConfiguration.getInstance();

                  final JbpmContext jbpmContext = jbpmConfig.createJbpmContext();

                  final GraphSession graphJbpm = jbpmContext.getGraphSession();

                  final ProcessDefinition processDef = graphJbpm.findLatestProcessDefinition("builder");

       

                  final ProcessInstance processInstance = processDef.createProcessInstance();

                  processInstance.getContextInstance().setVariable("packageConfigurationId", packageConfiguration.getId());

       

                  jbpmContext.save(processInstance);

                  pack.setJbpmProcessId(processInstance.getId());

                  processInstance.getContextInstance().setVariable("packLauncher", pack);

       

      ....

       

       

      @Observer("cancelBuilderObserver")

          public void cancelProcessForBuilder(final Package pack) {

              try {

                  final JbpmConfiguration jbpmConfig = JbpmConfiguration.getInstance();

                  final JbpmContext jbpmContext = jbpmConfig.getCurrentJbpmContext();

                  final GraphSession graphJbpm = jbpmContext.getGraphSession();

                  final ProcessDefinition processDef = graphJbpm.findLatestProcessDefinition("builder");

                  final ProcessInstance processInstance = graphJbpm.getProcessInstance(processDef.getId());

       

      ...

       

       

      But when I do jbpmConfig.getCurrentJbpmContext(); the value is null. It is probably due to different transactions.

      I just want to be able to end a processInstance using its id.

       

      Could you please help me?

       

      Thanks.
