EntityManager is null

[Robert Wheeler]

I have a very basic sample I am trying to insert a record into a database.
 I keep getting a NullPointer when I try to persist my record and when I
debug I see that the EntityManager is null.  I am including my
persistence.xml and blueprint.xml files and any help would be appreciated.
