- the name of the persistence unitmap
- a Map of properties for use by the
persistence provider. These properties may be used to
override the values of the corresponding elements in
the persistence.xml
file or specify values for
properties not specified in the persistence.xml
(and may be null if no properties are specified).EntityManagerFactory createContainerEntityManagerFactory(PersistenceUnitInfo info, java.util.Map map)

- metadata for use by the persistence providermap
- a Map of integration-level properties for use

are specified).
If a Bean Validation provider is present in the classpath,
the container must pass the ValidatorFactory
instance in
the map with the key "javax.persistence.validation.factory"
