At this point, we should specify the values for the
Class Name
and
Package
fields
(
Customer
and
com.ensode.jpaweb
in our example).
Projects using JPA require a persistence unit. This persistence unit is defined in a
file called
persistence.xml
. When we create our first JPA entity for the project,
NetBeans detects that no
persistence.xml
exists and automatically checks the
checkbox labeled
Create Persistence Unit
. The next step in the wizard allows us to
enter the necessary information to create the persistence unit.
