Error 420 "Can't call builtin routines remotely" while compiling a proc

Question

I get the message above when I try to compile a Forms procedure with a call to specific functions in the DBMS_UTILITY package. I am using Forms 10.1.2.2.0 and 10g DB (10.2.0.4.0). I want to trace the PL/SQL path that my Forms application is taking and be able to report the line number of the failure when an exception is thrown. I am able to call some routines within the DBMS_UTILITY package, but not any of them that have "pragma interface (C, format_error_stack);" in the code. These include format_call_stack, format_error_stack, and format_error_backtrace; all of which I would like to use. I've tried creating my own DB package function to act as a wrapper; this allows me to compile the form, but the call to the function form my exception handler returns null. These are really useful functions, but I do need to be able to access the functionality from within Forms. Does anyone have a solution/workaround for this problem. Note, this is similar to the question in Link:[ http://forums.oracle.com/forums/thread.jspa?messageID=504922��]
Thanks JK.

Nope, that does not work. See my first post above. I've tried using a wrapper, and whilst this allows my forms procedure to compile and my form to run, the wrapper procedure is returning null. Here's some code that may help to explain where I'm at. In the form, I've got -
DECLARE
    l_bt VARCHAR2(2000); -- BackTrace
BEGIN
    JEK_Raise_Exception; -- This is a DB procedure
EXCEPTION
   WHEN OTHERS THEN
      l_bt := KEYOWNER.Backtrace.generate_backtrace;
      message('l_bt = '||l_bt); pause;
END;-- Then a DB procedure that just generates an exception
CREATE OR REPLACE PROCEDURE JEK_Raise_Exception IS
BEGIN
   RAISE too_many_rows;
END;-- and the function from my Backtrace Package to return the backtrace data.
   FUNCTION generate_backtrace
       RETURN VARCHAR2
   IS
      l_bt      VARCHAR2(2000);
   BEGIN
       l_bt := DBMS_UTILITY.format_error_backtrace;
       RETURN l_bt;  -- In my testing so far this has been NULL!!!
   END;
