triggers...need help!!!

CREATE OR REPLACE TRIGGER validtable
BEFORE INSERT ON playerTables
FOR EACH ROW
BEGIN
IF (:new.tableNum < 10)
THEN RAISE_APPLICATION_ERROR(-20000, 'my error message');
END IF;
END;


----------------------------------------------------------
are these 3 lines supposed to print out or just my error message(ORA-20000)?

ORA-20000: my error message
ORA-06512: at "51723545.VALIDTABLE", line 3
ORA-04088: error during execution of trigger '51723545.VALIDTABLE'

ya they're supposed to be, you my be able to get rid of them? but i don't know. If you're accessing your database thru java you can just catch the errors
