Problems with dbms_output.put_line

I seem to have a problem with dbms_output.put_line command. I create a stored procedure as user XXX and given access to all other user to use the stored procedure and stuck some dbms_output message for the user to see. When I log into Oracle as user YYY and run the store procedure I don't see any of the dbms message out on the screen. Of course, I've check all the obivious, ie. set serveroutput on, set term on, set echo etc. Has anyone run into this problem?

Thanks for any help! Received on Wed Aug 27 1997 - 00:00:00 CDT
