EJB Postgres Primary Key Troubles

Question

I'm using Postgres 8.03 and have a table with a serial id (aka auto increment) as it's primary key.
Is there an easy way to handle the auto increment field with an EJB? Currently I have to manually set the Primary key during an insert. Is there a way to do an insert and let the auto increment do it's job without me having to manually set it?
Will I have to query to get the highest value in the primary key field?
The only other way I could think of to handle this would be to make the primary key field a var char and create a GUID each time I do an insert.
Thoughts on this would be great!
Thank you!

without me having to manually set it?you mean ejb3?
i used, when i migrated from hsqldb to postgresql, this kind of id generator
@SequenceGenerator(name = "board_sequence", sequenceName = "board_id_seq")
class Xyz....
@GeneratedValue(strategy = GenerationType.SEQUENCE)
getId() {
.....EJB3 will create a sequence on his own, so you can use it.
