and here is my code,

 public static void main(final String[] args) {

      boolean result;
      TeamPlatform.startup();
      try {
        result = run(args);
      }
      catch (TeamRepositoryException x) {
        x.printStackTrace();
        result = false;
      }
      finally {
        TeamPlatform.shutdown();
      }

      if (!result) {
        System.exit(1);
      }

    }

    private static boolean run(final String[] args) throws TeamRepositoryException {

      if (args.length != 7) {
        System.out
            .println("Usage: CreateWorkItem <repositoryURI> <userId> <password> <projectArea> <workItemType> <summary> <category>");
        return false;
      }

      String repositoryURI = "https://***************";
      String userId = "******************";
      String password = "***********************";
 
      ITeamRepository teamRepository = TeamPlatform.getTeamRepositoryService().getTeamRepository(repositoryURI);
      teamRepository.registerLoginHandler(new LoginHandler(userId, password));
      teamRepository.login(null);
      teamRepository.logout();

      return true;
    }
  }
