    problem with my first process execution

    baadr Newbie

      Hi !

      I'm a new user of JBOSS jbpm Worfkflow and I want to understand how it works so I tried to execute a  simple programme that instantiate a process defined in test.jpdl.xml:

       

      I'm using eclipse Helios as IDE.

       

       

      === Environment ==============================

      - jBPM Version : 4.3
      - Database : postgresql 8.4
      - JDK : 1.6
      - Container : ?
      - Configuration :jbpm.cfg.xml only using imports from the jbpm.jar
         lib itself
      - Libraries : jbpm4.3 libs
       

      === Process ==================================

      <?xml version="1.0" encoding="UTF-8"?>

       

      <process name="test" xmlns="http://jbpm.org/4.3/jpdl">

         <start name="start1" g="16,18,48,48">

            <transition name="to etape1" to="etape1" g="-25,-21"/>

         </start>

         <state name="etape1" g="96,16,92,52">

            <transition name="to java" to="java" g="-15,-20"/>

         </state>

         <java name="java" g="220,16,92,52" class="Methode" method="invokeMe()">

            <transition name="to end1" to="end1" g="-19,-19"/>

         </java>

         <end name="end1" g="344,18,48,48"/>

      </process>



      === API ===================================

      import org.jbpm.api.Configuration;

      import org.jbpm.api.ExecutionService;

      import org.jbpm.api.HistoryService;

      import org.jbpm.api.ManagementService;

      import org.jbpm.api.ProcessEngine;

      import org.jbpm.api.ProcessInstance;

      import org.jbpm.api.RepositoryService;

      import org.jbpm.api.TaskService;

       

       

      public class Exec {

       

          /**

           * @param args

           */

          public static void main(String[] args) {

              // TODO Auto-generated method stub

              ProcessEngine processEngine = new Configuration().buildProcessEngine();

              RepositoryService repositoryService = processEngine.getRepositoryService();

              ExecutionService executionService = processEngine.getExecutionService();

              TaskService taskService = processEngine.getTaskService();

              HistoryService historyService = processEngine.getHistoryService();

              ManagementService managementService = processEngine.getManagementService();

              ProcessInstance processInstance = executionService.startProcessInstanceByKey("test");

       

              String deploymentId = repositoryService.createDeployment()

              .addResourceFromClasspath("test.jpdl.xml")

              .deploy();

       

          }

       

      }



      === Stacktrace ==============================
