problem with returning a table - Mailing list pgsql-jdbc

Hi everybody,

There is a  function that returns a table.  I set out parameter's type
to  Types.OTHER but When I call the function in java, returning type is
returned as INTEGER .

Here is the function:

CREATE OR REPLACE FUNCTION sube_getir(int4, "varchar")
RETURNS SETOF subeler AS
$BODY$
DECLARE
id ALIAS FOR $1;
ad ALIAS FOR $2;
ref record;

BEGIN
  IF (id=0)AND(ad='') THEN
      for ref in SELECT * FROM subeler loop
          RETURN NEXT ref;
      end loop;
      return;

  ELSEIF (ad='') THEN
      for ref in SELECT * FROM subeler WHERE "HESAP_SUBE_ID"=id loop
      return next ref;
       end loop;
       return;
  ELSE
       for ref in SELECT * FROM subeler WHERE "HESAP_SUBE_ADI"=ad loop
      return next ref;
       end loop;
       return;
  END IF;
 END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
ALTER FUNCTION sube_getir(int4, "varchar") OWNER TO postgres;

--------calling function in java:

sc = conn.prepareCall("{ ? = call sube_getir( ? , ? ) }");
          sc.registerOutParameter(1,Types.OTHER);
          sc.setInt(2,4);
          sc.setString(3,"");
          sc.execute();
          rs = (ResultSet)sc.getObject(1);
