Answer 1

have somebody has any idea how can i do itWe can't help you much because you are using many other classes.... but there is glaring error which I would like to point to, i.e.:
             arguments = new ArrayList();
arguments.remove(id = 1);Just after initializing the ArrayList you are removing the second element, that would surely throw Exception.
I think instead of arguments.remove(1) you have to use:
arguments.add(id = 1);
//OR
arguments.remove(String.valueOf(id=1));But I can't say, I don't know what 'callUpdateProcedure' expects.
Thanks!
