Answer 1

First, there are two things to check, first the version, this is valid since 9iR1 and greater. Second, once you have verified your version let's see this example, check the syntax you are using to issue your command:
set termout off
set pages 999
SET MARKUP HTML ON TABLE "class=emp cellspacing=0" ENTMAP OFF
col emp_name format a30 heading "<p class=left>Emp Name</p>"
col salary   format $999,999 heading "<p class=left>Salary</p>"
spool my_html.htm
select
   emp_name,
   salary
from
   emp e;
spool off;This will spool the HTML to the my_html.htm file, ready for you to return to the client.
