Accessing function's return value

Question

Hi there. I have created several pl/sql procedures and functions that I can run as standalone programs and I have no problem integrating them into my java code also. However I cannot access the return value of any created function from my java code. The functions appear to execute correctly because when I deliberately enter an invalid select statement I get the errors I expect to get for that instance nad if I enter a valid select statement in the function the program executes correctly but I still cannot access the function's return value. My java code where I execute the pl/sql function is as follows:
CallableStatement p = cont.conn.prepareCall("{call ? := Hellen.FUNC}");
p.setString(1, "z006"); //hellen.FUNC = function name
p.execute();
How do I access the return value of my function?
Do I need to get a ResultSet?
My function is as follows:
function func
return varchar
is tester varchar(4);
BEGIN
select cfcc_code into tester from hellen.test1 where test1.cfcc_code = 'A21';
return tester;
END;
Any help will be gratefully received, Joe

You need to do something like
p.registerOutParameter(1, java.lang.String);
p.execute();
String result = p.getString(1);Cheers, APC
