Not able to create a text file in Client Machine using Forms 10g

Question

Hi - I'm mot able to create a text file in Client Machine using Forms 10g. I'm getting error when system executes the bolded line.(i.e. CLIENT_TEXT_IO.FOPEN). During run-time system is throwing "ORA-06508: PL/SQL: could not find program unit being called".
I had attached webutil.pll in the form.
Please advise me.
DECLARE
l_Temp CLIENT_TEXT_IO.FILE_TYPE;
LC$Name Varchar2(100) ;
LC$Fic Varchar2(100) ;
LN$Lines Pls_integer := 0 ;
LC$Line Varchar2(4000) ;
Cursor C_CUR Is
Select * From TEST_TEXTIO where rownum <= 50;
BEGIN
LC$Name := 'tmp_file.txt' ;
LC$Fic := 'c:\temp\tmp_file.txt';
Begin
l_temp := CLIENT_TEXT_IO.FOPEN( 'C:\temp\tmp_file.txt', 'W');
Exception
     when others then
     message( 'OPEN FILE ERROR ' || LC$Fic ||sqlerrm );
     display_error;
     raise form_trigger_failure;
End ;
-- Write the lines --
For Cur In C_CUR Loop
     LC$Line := Cur.CODE || ' -> ' || Cur.COL1 || ',' || Cur.COL2 || ',' || Cur.Col3 ;
     CLIENT_TEXT_IO.PUT_LINE( LF$File, LC$Line ) ;      
     LN$Lines := C_CUR%ROWCOUNT ;
End loop ;
-- Close the file --
CLIENT_TEXT_IO.FCLOSE( LF$File ) ;
Exception
     When others Then
message('err='||sqlerrm);message(' ');
display_error;
CLIENT_TEXT_IO.FCLOSE( LF$File ) ;      
     Raise ;
END;
Thanks.

Hi ,
i have one Question though its not related to thos question if some could help me it will be really helpful,
i have created one program to import and export excel to forms vice versa, if the form is attached with webutil its working fine am using ole2.but i have a new idea if i add this program in menu, it can be used for all the forms attched to that menu, i made program also, but problem am facing right now is if the form is not attched with webutil it will not work so is there possiblity to share my webutil from one form to another form ,so i will keep one form as a interface form in that webutil will be attched ,i can share that webutil to all other forms so that all the forms no need to attach webutil again
if its possible means please suggest some ideas
