    contiunous JBPM errors

    m owens Newbie

      Hi,

      I am writing a JBPM implmentation for a corporate system. Currently I am not deploying to an application server I am running the process locally as a set of unit tests. I am deploying the process definitions manually. Below is the code for the unit tests:

      public class testProcessManager
      {

      @BeforeClass
      public static void setup()
      {
      LBSJbpmInstance.createSchema();
      }

      @Test
      public void testCreateDefinition()
      {
      JbpmContext context = JbpmConfiguration.getInstance().createJbpmContext();

      try
      {
      URL u = this.getClass().getResource("/com/ProcessDefinition.xml");
      File f = new File(u.getFile());

      ProcessDefinition definition = ProcessDefinition.parseXmlReader(new FileReader(f));
      context.getGraphSession().deployProcessDefinition(definition);
      }
      catch (FileNotFoundException e)
      {
      Assert.fail(e.getMessage());
      }
      finally
      {
      context.close();
      }

      }

      @Test
      public void testCreateInstance()
      {
      JbpmContext jbpmContext = JbpmConfiguration.getInstance().createJbpmContext();

      try
      {
      ProcessDefinition processDefinition = jbpmContext.getGraphSession().loadProcessDefinition(1);

      ProcessInstance processInstance = new ProcessInstance(processDefinition);

      ContextInstance contextInstance = (ContextInstance) processInstance.getContextInstance();
      contextInstance.createVariable("test", "test");

      processInstance.signal();

      jbpmContext.save(processInstance);
      }
      catch (Throwable t)
      {
      t.printStackTrace();
      Assert.fail(t.getMessage());
      }
      finally
      {
      jbpmContext.close();
      }
      }

      @AfterClass
      public static void teardown()
      {
      JbpmConfiguration.getInstance().dropSchema();
      }
      }


      This code throws the error: org.jbpm.JbpmException: closed JbpmContext in different order then they were created. This does not happen if i remove the processInstance.signal invocation.

      Can anyone explain the nature of this error.

      Thanks in advance

          after creation put a saveandreload before the signalling. See jBPM unittests where this is also done.

            Hi Ronald,

            Thanks for the quick response. Ok, im new to jbpm so don't really understand that response. Where can I get the latest jbpm unit tests? I'm using version 3.2.2.

            I found unit tests for 3.1.2 and located the save and reload method. I copied the code from there into my test and unfortunately it still doesn't work - i get exactly the same error (code below):

            @Test
            public void testCreateInstance()
            {
            JbpmContext jbpmContext = JbpmConfiguration.getInstance().createJbpmContext();

            try
            {
            ProcessDefinition processDefinition = jbpmContext.getGraphSession().loadProcessDefinition(1);

            ProcessInstance processInstance = new ProcessInstance(processDefinition);

            ContextInstance contextInstance = (ContextInstance) processInstance.getContextInstance();
            contextInstance.createVariable("test", "test");

            jbpmContext.save(processInstance);
            jbpmContext.close();
            jbpmContext = JbpmConfiguration.getInstance().createJbpmContext();
            processInstance = jbpmContext.loadProcessInstance(processInstance.getId());

            processInstance.signal();
            }
            catch (Throwable t)
            {
            t.printStackTrace();
            Assert.fail(t.getMessage());
            }
            finally
            {
            jbpmContext.close();
            }
            }

            Any help would be much appreciated

              the latest unittests are in CVS. The 3.2 release does not include the source anymore.

                Could you please specify where i get the CVS url from? Im connecting to the JBPM source using fisheye and the unit tests specified within JBPM 3 (:/jbpm.3/test/jbpm/org/jbpm/graph/def/ProcessDefinitionDbTest.java ) in there are over 2 years old.

                Am i looking in the correct place?
                Thanks

                  make sure you see the only cvs-head files. The files you show are moved to a different location. :/jbpm.3/jpdl/jar/src/test
