Fnd_user_pkg.changepassword failing

Question

I have access to the fnd_user_pkg.changepassword function and I can't seem to get it to commit. I'm using the SQL statement below with no success. It completes but the password does not actually change. I have changed the user name below for this posting but I know that the user I have chosen does actually exist. I have put the commit statement in two different places just testing this out. I imagine that the function should commit internally but I'm not sure.
Any advice?
Thanks!
DECLARE
CURSOR c_users IS
SELECT user_name FROM fnd_user WHERE user_name = 'MyUserName';
v_user c_users%ROWTYPE;
v_success BOOLEAN;
BEGIN
OPEN c_users;
FETCH c_users
INTO v_user;
WHILE c_users%FOUND
LOOP
v_success := apps.fnd_user_pkg.changepassword(v_user.user_name,
'MyNewPassword');
COMMIT;
IF v_success != TRUE
THEN
dbms_output.put_line('Failed to set password for user ' ||
v_user.user_name);
END IF;
FETCH c_users
INTO v_user;
END LOOP;
CLOSE c_users;
COMMIT;
EXCEPTION
WHEN OTHERS THEN
ROLLBACK;
dbms_output.put_line('Error');
END;

Does anyone know which one should be used and why? Private vs public?
always use the public api. You are not supposed to use the private ones.
