Hi,

I am getting started with jBPM and am following the link  http://docs.jboss.org/tools/2.0.0.GA/jbpm/en/html/Test_Drive_Proc_Development.html http://docs.jboss.org/tools/2.0.0.GA/jbpm/en/html/Test_Drive_Proc_Development.html.

I created the junit test file and am trying to test the process.  I am however getting the following error:

[code]

[/code]

Here is my test case code:

[code]

package com.jbay;

import junit.framework.TestCase;
import org.jbpm.graph.def.ProcessDefinition;
import org.jbpm.graph.exe.ProcessInstance;
import org.jbpm.jpdl.xml.JpdlXmlReader;

import junit.framework.TestCase;

public class HiTest extends TestCase {

    public void testProcess() throws Exception{

        ProcessDefinition definition = ProcessDefinition.parseXmlResource("hi/processdefinition.xml");
        assertNotNull("Definition should not be null", definition);

        ProcessInstance instance = new ProcessInstance(definition);
        assertEquals(
                "Instance is in start state", instance.getRootToken().getNode().getName(), "start");

        instance.signal();
        assertEquals(
                "Instance is in start1 state", instance.getRootToken().getNode().getName(), "start1");

        instance.signal();
        assertEquals(
                "Instance is in end state", instance.getRootToken().getNode().getName(), "end1");

        assertTrue("Instance has ended", instance.hasEnded());


    }

}

[/code]

And my process definition that I created:

[code]

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

<process-definition
  xmlns="urn:jbpm.org:jpdl-3.2"  name="jBay">
   <start-state name="start">
      <transition name="toauction" to="state1"></transition>
   </start-state>
   <state name="state1">
      <transition name="tr1" to="end1"></transition>
   </state>
   <end-state name="end1"></end-state>
</process-definition>

[/code]

I am not sure what the error means.  I checked the exception code:

[code]

if (Problem.containsProblemsOfLevel(problems, Problem.LEVEL_ERROR)) {
      throw new JpdlException(problems);
    }

    if (problems!=null) {
      Iterator iter = problems.iterator();
      while (iter.hasNext()) {
        Problem problem = (Problem) iter.next();
        log.warn("process parse warning: "+problem.getDescription());
      }
    }

[/code]

I am not sure this is helping me. I renamed the states and transitions to include only letters in order to correct the parsing, but it still gave out the same error.  ANy help would be  nice.

Thanks!
