Alan - You are correct. However, apparently that isn't easy to do with J2EE
/ EJB, hense the trigger. Don't ask me why. When will they come out with a
book titled:

You could also do it as part of your insert statement if you didn't want to
use a trigger.
INSERT INTO employees
VALUES (employees_seq.nextval, 'John', 'Doe', 'jdoe',
'555-1212', TO_DATE(SYSDATE), 'PU_CLERK', 2500, null, null,
30);
Same thing goes with currval also.
