i found somebody override setProperty to be able to add array in this link setParameter for an array property with JACOB my code was this

public static void setProperty(Dispatch d, String sName, String sIndex, String sValue) {
      Variant av[] = { new Variant(sIndex), new Variant(sValue) };
      int j[]= {0};
      Dispatch.invokev(d, sName, Dispatch.Put, av,j).safeRelease();
      av[0].safeRelease(); av[1].safeRelease();
      }

and calling was like this

this.setProperty(zkem,"CardNumber","0","2599970");

before this line

Variant vResult = Dispatch.call(zkem,"SetUserInfo",dwMachineNum, dwEnrollNo, dwUserName, dwPassword, dwPrivelage,true);
