Hello, i have a problem with started a process JBPM by an method of an Class with a method public static main. I have created a project JBPM with maven and this project have an bpmn with inside a start a script and end.Then this jar i deployed into jbpm-console (KIE Workbench)with deployed Units (groupId,Artifact and Version). Then, by my eclipse i invoked this process with a method public static and below my code java:

public class Test {

    public static void main(String[] args) {

        try{

            String deploymentId = "richieste-portale:richieste-portale:1.0.0-SNAPSHOT";

            URL appUrl = new URL("http://localhost:8080/jbpm-console/");

            String user = "admin";

            String password = "admin";

            new Test().startProcessAndHandleTaskViaRestRemoteJavaAPI(appUrl, deploymentId, user, password);

        }catch(Exception e){

            e.printStackTrace();

        }

    }

    public void startProcessAndHandleTaskViaRestRemoteJavaAPI(URL instanceUrl, String deploymentId, String user, String password) {

          RemoteRuntimeEngineFactory restSessionFactory  = new RemoteRestRuntimeFactory(deploymentId, instanceUrl, user, password);

          // Create KieSession and TaskService instances and use them

          RemoteRuntimeEngine engine = restSessionFactory.newRuntimeEngine();

          KieSession ksession = engine.getKieSession();

          TaskService taskService = engine.getTaskService();

          ProcessInstance processInstance = ksession.startProcess("com.sample.bpmn.hello");

          long procId = processInstance.getId();

          String taskUserId = user;

          taskService = engine.getTaskService();

          List<TaskSummary> tasks = taskService.getTasksAssignedAsPotentialOwner(user, "en-UK");

          long taskId = -1;

          for (TaskSummary task : tasks) {

            if (task.getProcessInstanceId() == procId) {

              taskId = task.getId();

            }

          }

          if (taskId == -1) {

            throw new IllegalStateException("Unable to find task for " + user + " in process instance " + procId);

          }

          taskService.start(taskId, taskUserId);

        }

}

but i get this error:

I have change method. Now my news code java is:

	String deploymentId = "test-jbpm:1.0.0-SNAPSHOT";
	URL appUrl = new URL("http://localhost:8080/jbpm-console");
	String user = "admin";
	String password = "admin";
	RemoteRestRuntimeFactory restSessionFactory
	= new RemoteRestRuntimeFactory(deploymentId, appUrl, user, password);
	RemoteRuntimeEngine engine = restSessionFactory.newRuntimeEngine();
	KieSession ksession = engine.getKieSession();
	TaskService taskService = engine.getTaskService();
	AuditLogService auditLogService = engine.getAuditLogService();
	Map<String, Object> params = new HashMap<String, Object>();
	params.put("candidate", "johny");
	ProcessInstance processInstance = ksession.startProcess("com.sample.bpmn.hello", params);

but now i get other error:
