placing the necessary files, I able to start the human task service via JBoss : *Now I want my +jbpm task+ run using this service as under:*                     // load up the knowledge base

objWSHuman= new WSHumanTaskHandler();                       objWSHuman.setConnection("127.0.0.1", 9123);                  ksession.getWorkItemManager().registerWorkItemHandler("Human Task",objWSHuman);                  // start a new process instance                  Map<String, Object> params = new HashMap<String, Object>();                  params.put("employee", "rajan");                  params.put("reason", "Yearly performance evaluation");                  ksession.startProcess("com.sample.evaluation", params);                  System.out.println("Thats itt..");
