Pl/sql web service returning a list of results

Question

I am able to publish a pl/sql package as a web service that returns a single result. However, when I try to return a list of results, I get an error in jdeveloper when I select the package and invoke publish as web service.
I use a simple pl/sql package:
create type longcredit_obj as object (
credit varchar2(200),
parlrepid number(6),
mbrid number(6),
rdgid number(6))
create type longcredit_list as table of longcredit_obj
create or replace package longcredit_pck as
function get_longcredit (initials in varchar2) return longcredit_list;
end longcredit_pck;
create or replace package body longcredit_pck as
function get_longcredit (
initials in varchar2) return longcredit_list
as
i integer;
list longcredit_list;
cursor c_credit is
select a.credit, a.parlrepid, a.mbrid, a.rdgid
from member_credits_test_vw a
where upper(init) = upper(initials);
begin
list := longcredit_list();
for rec in c_credit
loop
i:= list.last;
list(i) := longcredit_obj(null, null, null, null);
list(i).credit := rec.credit;
list(i).parlrepid := rec.parlrepid;
list(i).mbrid := rec.mbrid;
list(i).rdgid := rec.rdgid;
end loop;
return list;
end get_longcredit;
end longcredit_pck;
Is this a feature that is available?
Any suggestions are appreciated.
Thank you in advance.

I am running jdeveloper 10.1.3.2.0 and database v. 10.1.0.4.0.

Hi Steffen,
I did manage to get it to work by doing the following:
drop type longcredit_list
drop type longcredit_obj
create type longcredit_obj as object
(credit varchar2(200),
parlrepid number(6),
mbrid number(6),
rdgid number(6))
create type longcredit_list as table of longcredit_obj
create or replace package longcredit_pck as
function get_longcredit(initials in varchar2) return longcredit_list;
end longcredit_pck;
create or replace package body longcredit_pck as
function get_longcredit(initials in varchar2) return longcredit_list
as
v_longcredit_obj longcredit_obj:=longcredit_obj(null,null,null,null);
v_longcredit_list longcredit_list:=longcredit_list();
i number:=1;
cursor getlist is
select distinct a.credit, a.parlrepid, a.mbrid, a.rdgid
from member_credits_test_vw a
where upper(init) = upper(initials)
order by a.parlrepid;
begin
for rec in getlist loop
v_longcredit_obj.credit := rec.credit;
v_longcredit_obj.parlrepid := rec.parlrepid;
v_longcredit_obj.mbrid := rec.mbrid;
v_longcredit_obj.rdgid := rec.rdgid;
v_longcredit_list.extend;
v_longcredit_list(i):=v_longcredit_obj;
i:=i+1;
end loop;
return v_longcredit_list;
end get_longcredit;
end longcredit_pck;
Also, before deploying, in jdeveloper, in the deploy file, I select the property filters under web-inf\classes and check all the classes that are unchecked (see thread id 505217).
Also, the database I'm using now is v. 10.2.0.3.0.
Thanks for your suggestion!
Carmen.
