Hello everybody,
I'm  using JBoss AS 7.1.1 and jBPM 5.4.
I was trying to define my custom process "Run Action".
*1)* I created my "MyProcessesDefinition.conf" file:
import org.drools.process.core.datatype.impl.type.ObjectDataType;
import org.drools.process.core.datatype.impl.type.StringDataType;
import org.drools.process.core.datatype.impl.type.IntegerDataType;
[
  // my workItem
  [
    "name" : "RunAction",
    "parameters" : [
      "Command" : new StringDataType(),
      "Parameters" : new ObjectDataType(),
    ],
    "results" : [
      "ExitValue" : new IntegerDataType(),
    ],
    "displayName" : "RunAction",
    "icon" : "icons/operation.ico"
  ]


]
*2)* I created my "drools.rulebase.conf"
drools.workDefinitions = MyProcessesDefinition.conf WorkDefinitions.conf
*3)* I created the the RunAction handler

public class RunActionHandler implements WorkItemHandler {


          @Override
          public void abortWorkItem(WorkItem workItem, WorkItemManager manager) {
                    // extract parameters
              String command = (String) workItem.getParameter("Command");

              HashMap parameters = (HashMap) workItem.getParameter("Parameters");


              // run command 

              String command_with_params =command;
              Runtime runtime = Runtime.getRuntime();
              Process process = null;

              System.out.println("okkk");


              Map<String, Object> result = new HashMap<String, Object>();

               result.put("ExitValue", new Integer (0));

              // notify manager that work item has been completed

             manager.completeWorkItem(workItem.getId(), result);

          }


          @Override
          public void executeWorkItem(WorkItem arg0, WorkItemManager arg1) {
                    // Se invio un Ctrl+C interrompo il task????
          }

}

*4)*I created the process depicted in the attachement
*5)* I wrote the following main:
public class ProcessMain {

          public static final void main(String[] args) throws Exception {
                    // load up the knowledge base
                    KnowledgeBase kbase = readKnowledgeBase();
                    StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();

                    ksession.getWorkItemManager().registerWorkItemHandler("RunAction", new RunActionHandler());

                    Map<String, Object> params = new HashMap<String, Object>();
                    Object workflowName= new String ("C:\test.bat"), Properties = new String("");
                    params.put("Command", workflowName);
                    params.put("Parameters", Properties);

                    // start a new process instance
                    ksession.startProcess("wkfRepository.singleTaskWkf", params);
                    System.out.println("Process started ...");
          }


          private static KnowledgeBase readKnowledgeBase() throws Exception {
                    KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
                    kbuilder.add(ResourceFactory.newClassPathResource("SingleTaskWkf.bpmn"), ResourceType.BPMN2);
                    return kbuilder.newKnowledgeBase();
          }  
}

When I start the JBoss server, and run the the java application the process ends, but the custom process does not start (the "okkk" message is NOT printed).

Can anyone help me?
