Hi,
I am trying to create a new app in Glassfish V3 with JSF2, et al. To get access to an entity manager the following code seems to be used by most of the examples.
@PersistenceContext(unitName="abc")
EntityManager em;
Where the abc persistence unit is defined in a persistence.xml file.
How can I define a default persistent unit to be used so that I can write code like
@PersistenceContext
EntityManager em;
It's important that I don't hard wire the unitName in the code as some of these a relibraries that will be used by multiple applications.
Once again any help would be much appreciated.
Regards.
