Hy, I have problem calling a procedure in Oracle. My procedure is like the next:

PROCEDURE CloseEpisode(P_CURSOR out sys_refcursor,P_EPIS_ID IN INTEGER)
AS
BEGIN
DELETE FROM sene1_visitas WHERE sene1_visitas.VISI_EPIS_ID = P_EPIS_ID;
OPEN P_CURSOR FOR SELECT EPIS_ID, EPIS_EPISODIO
FROM sene1_episodios where sene3_episodios_ant.EPIS_ID= P_EPIS_ID;
END;

I have the next doubts:

1. I am using the cursor because I am calling this procedure from Hibernate and the documentation says that you have to return a resulset. I cant return anything because its a procedure, right? So the cursor I am using is ok, right?
2. So the format call for the prodecure I am using {?=call closeEpisodio(?,?)}, is it right?
3. In my java code I have done the next things:
- if I setInt(2, Integer of EpisId) I get : IllegalArgumentException Positional parameter does not exist: 2 in query: {?=call cerrarEpisodio(?,?)}. .
-if I setInt(1, Integer of EpisId) I get the error java.lang.ArrayStoreException.
4. Do I have to set other parameters?

What is wrong?

Thanks
