The question basically sums it up.
Play framework has the JPABase class that JPA beans inherit from. This class has a method called em() which returns the bean’s entityManager instance. Is there something equivalent to this in plain JPA?

AFAIK, no. And I would find it very questionable. JPA entities are supposed to be POJOs usable outside of the persistence layer, where the JPA classes are not even in the classpath. Exposing the EntityManager in those POJOs seems wrong to me.
