SQL & PL/SQL :: DBMS_JOBS Procedure Has 3 Variable Out Arguments

I am using ORACLE SQL developer.. I am trying to schedule a package to run daily..here is the overview of my package..
-----
create or replace
PACKAGE BODY xxx_MTO_yyy
AS
PROCEDURE yyy_mto (p_message OUT VARCHAR2, p_detail OUT VARCHAR2, p_value OUT VARCHAR2) IS
XXXXXX
CXXXXXX
XXXXXXX
END yyy_mto;
end xxx_MTO_yyy;

Now I created schedule as shown (The sql is processed)

begin
dbms_scheduler.create_schedule
(schedule_name => 'MTO_DAILY',
start_date=> trunc(sysdate)+6/24, repeat_interval=> 'FREQ=DAILY; BYDAY=MON,TUE,WED,THU,FRI,SAT,SUN; BYHOUR=22;',
comments=>'Runtime: Every day (Mon-Sun) at 6:00 );
END;

Now I am creating SCHEDULER PROGRAM as shown (sql processed)

begin
dbms_scheduler.create_program
(program_name=> 'mto_DATA',
program_type=> 'STORED_PROCEDURE',
program_action=> xxx_MTO_yyy.yyy_mto',
enabled=>true,
comments=>'Procedure to collect session information'
);
end;

Now i am creating the scheduler jobs as shown (here also the sql processed)

begin

dbms_scheduler.create_job
(job_name => 'str_data',
program_name=> 'mto_DATA',
schedule_name=>'MTO_DAILY',
enabled=>true,
auto_drop=>false,
comments=>'nil');
end;

Now I have two questions.

a) the job should have been visible under the "jobs" tab in sql developer. I dont see that.
b) When I tried to run the job manually using
**********
(BEGIN
DBMS_SCHEDULER.RUN_JOB (
JOB_NAME =>'STR_DATA'
);
END;

it failed , saying that "ORA-06553: PLS-ORA-06553: PLS-306: wrong number or types of arguments in call to 'yyy_MTO'". When defining the "dbms_ scheduler. create_program" object , how can I define the arguments?. My procedure has 3 variable out arguments?
