PL/SQL :: How To Get More Than 4000 Characters Per Field

I am using Oracle Version 11.2. Here's an example of what I am trying to do..

-- create table with a clob column
create table sr_test
(c1 CLOB)

-- load data that is more than 4000 characters into clob
declare
var1 varchar2(32000);
begin
var1:= '';

for i in 1..5000 loop
var1:= var1||i||',';

end loop;
dbms_output.put_line(var1);
insert into sr_test(c1) values (var1);
end;

-- select table to make sure clob is loaded

select c1, dbms_lob.getlength(c1) from sr_test

-- create procedure to return data from table

create procedure sr_p1(result out sys_refcursor)
is
begin
open result for
select c1 from sr_test;
end;

-- run the procedure to get data

DECLARE
RESULT sys_refcursor;

BEGIN
RESULT := NULL;

ACCOUNTING.SR_P1 ( RESULT );

:rc0_RESULT := RESULT;

END;

Everything works as intended. However, this procedure is being called from Webservices. According to what I have been told, webservices adds 18ms for each clob that needs to be converted into char so it can be displayed on the screen. So, I need something like this

create procedure sr_p1(result out sys_refcursor)
is
begin
open result for
select dbms_lob.substr(c1,32000,1) from sr_test;
end;

Is there an alternate method to send more than 4000 characters in the refcursor?
