WebService procedure with dbms_output.chararr OUT Parameters

Question

Hi everyone,
I'm using Oracle native web service and everything work fine. Anyway, we want to return the data through string array , Is it possible?
I already tried to create procedure as this script.
P_INPUT1 VARCHAR2,
P_INPUT2 VARCHAR2,
Result OUT dbms_output.chararr
Is it possible to wrap it as to web service because I cannot see the wsdl from this package or there are the limitation or any workaround to solve this problem.
Thank and regards,
zenoni

Hi,
Result OUT dbms_output.chararrUse SQL object types instead.
For example :
create or replace type my_collection is table of varchar2(4000);
create or replace type my_ot is object ( list my_collection );
create or replace procedure genList(p_val_max in number, result out my_ot)
is
begin
  -- return a collection of numeric strings from 1 to p_val_max
  select my_ot(
           cast(
             multiset(
               select to_char(level)
               from dual
               connect by level <= p_val_max
             as my_collection
  into result
  from dual;
end;
/results in the following WSDL :
