Playing a bit with the "microcontainer-deployment" example of the
"jboss-EJB-3.0_Embeddable_ALPHA" distribution package I noticed the em.persist
throws an exception if I change
@Id(generate=GeneratorType.AUTO)
public int getId()
{
return id;
}
to
@Id(generate=GeneratorType.NONE)
public int getId()
{
return id;
}
in the Customer class and try to assign manually the PK in the CustomerDAOBean
class
public int createCustomer(String name)
{
Customer cust = new Customer();
cust.setId(1); // ADDED THIS!
cust.setName(name);
em.persist(cust);
return cust.getId();
}
The Exception is little explanatory:
