"Mail Merge" example on XE: Result ERROR?

Question

I used Mail Merge example to generate MSWord documents. Now I tray this on Oracle XE and got this:
"FORBIDDEN The requested operation is not allowed"
is it possible to execute procedure through URL with XE?

Answer 1

Security has been tightened in Oracle XE production,you have to "allow" your stored procedure to be executed.
See the documentation here: http://download-uk.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25309/adm_wrkspc.htm#BEJCGJFJ
Here is a working example using the schema HR:
conn HR/<pwd>@xe
create or replace procedure hello_world as
begin
  htp.p('hello world');
end;
grant execute on hello_world to anonymous
conn SYSTEM/<pwd>@xe
alter session set current_schema=FLOWS_020100;
CREATE OR REPLACE function wwv_flow_epg_include_mod_local(
    procedure_name in varchar2)
return boolean
is
begin
    -- Administrator note: the procedure_name input parameter may be in the format:
    --    procedure
    --    schema.procedure
    --    package.procedure
    --    schema.package.procedure
    -- If the expected input parameter is a procedure name only, the IN list code shown below
    -- can be modified to itemize the expected procedure names. Otherwise you must parse the
    -- procedure_name parameter and replace the simple code below with code that will evaluate
    -- all of the cases listed above.
    if upper(procedure_name) in (
          'HR.HELLO_WORLD') then
        return TRUE;
    else
        return FALSE;
    end if;
end wwv_flow_epg_include_mod_local;
/call it via http://127.0.0.1:8080/apex/hr.hello_world
