Hello,
Yeah , I got the solution using DBMS_PIPE function,I
followed following steps.
1. Pipe is created. see below procedure.
create or replace procedure proc_testpipe as
     v_pipe_integer          integer;
     v_pipe_message          integer;
begin
     v_pipe_integer := DBMS_PIPE.Create_Pipe('adipipe');
     dbms_pipe.pack_message('Hello Adinath Kamode,Message
     from Pipe');
     v_pipe_message := dbms_Pipe.Send_message('adipipe');
     end;
end;
2. then I created one Function which will obtain message from
Pipe and
will return value to form.
create or replace function proc_callpipe return varchar2 as
v_msg          integer;
v_rem          integer;
v_message          varchar2(500);
begin
v_msg:=dbms_pipe.receive_message('adipipe');
dbms_pipe.unpack_message(v_message);
dbms_pipe.purge('adipipe');
v_rem := dbms_pipe.remove_pipe('adipipe');
return(v_message);
end;
3. Last I called this function from form.
Cheers .. !
