How to Implement Management Chain in External routing Service

Question

hi,
I am using External Routing Service to Assign & route the tasks.
I will get the authorisation workflow in our external Routing class , Now I am suppose to implement that workflow in BPM worklist for that human task.
One way is to know the way to implement management chain in the External Routing Service.
I have found some BPEL classes for doing the same eg. ParticipantsType.ManagementChain, objFactory.createParticipantsTypeManagementChain().
But not able to find any sample code to implement.
Does any body knows how to implement the same.
Is their any other way to resolve this issue.
you can also refer the following thread to understand the problem statement: PROGRAMMATICALLY PERSISTING THE APPROVAL WORKFLOW FOR A HUMAN TASK.
thanks

I have tried the below mentioned code for implemnting management chain...
     private Participants createParticipant() {
          System.out.println("1");
          String user = users[numberOfApprovals++];
          ObjectFactory objFactory = new ObjectFactory();
          Participants participants = objFactory.createParticipants();
          participants.setIsAdhocRoutingSupported(false);
               StageType stage = objFactory.createParticipantsTypeStage();
               stage.setName("Stage1");
               System.out.println("2");
               SequentialParticipant seqParticipant = objFactory.createParticipantsTypeSequentialParticipant();
               seqParticipant.setName("Stage1.Participant1");
               System.out.println("3");
               ListType listType = objFactory.createList();
               ManagementChainListType managementListType = objFactory.createManagementChainListType();
               // adding Resource in the management chain
               ResourceType resourceChain = objFactory.createResourceType("fkafka");
               resourceChain.setIsGroup(false);
               resourceChain.setType("STATIC");
               resourceChain.setIdentityType("user");
               managementListType.getResource().add(resourceChain);
               System.out.println("4");
               // adding levels in the management chain
               ParameterType levelParameterType = objFactory.createParameterType("2");
               levelParameterType.setType("STATIC");
          managementListType.setLevels(levelParameterType);
               System.out.println("5");
               // adding title in the management chain                    
               ParameterType titleParameterType = objFactory.createParameterType("Vice President");
               titleParameterType.setType("STATIC");
               managementListType.setTitle(titleParameterType);
               System.out.println("6");
               listType.setManagementChain(managementListType);
               System.out.println("7");
               seqParticipant.setList(listType);
               System.out.println("8");
               stage.getParticipantOrSequentialParticipantOrAdhoc().add(seqParticipant);
               System.out.println("9");
          participants.getParticipantOrSequentialParticipantOrAdhoc().add(stage);
          System.out.println("10");
          return participants;
The above code doesnot give error during execution but It doesnot work, what It's suppose to be...
what It does is..It calls onInitiation method number of times [equal to the number of levels given in hierachy +1] at one shot. without being assigned to anybody and come out of the human task.
please let me know..If am missing something...
thanks
