Figure 2.5. The
BidService
EJB invokes the
addBid
method of
BidDao
and passes a
Bid
object. The
BidDao
invokes the persist method of
EntityManager
to save the
Bid
entity into the database. When the transaction
commits, you'll see that a corresponding database record in the
BIDS
table will be stored.
