It is invoked by the container in Java EE environments and
by the Persistence
class in Java SE environments to

Persistence
class when an
EntityManagerFactory
is to be created.emName
- 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)
EntityManagerFactory
is to be created.info
- metadata for use by the persistence providermap
- a Map of integration-level properties for use
by the persistence provider (may be null if no properties
are specified). These properties may include properties to
control schema generation.
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"
.
If the containing archive is a bean archive, the container
must pass the BeanManager instance in the map with the key
"javax.persistence.bean.manager"
.void generateSchema(PersistenceUnitInfo info, java.util.Map map)
Called by the container when schema generation is to occur as a separate phase from creation of the entity manager factory.

also include provider-specific propertiesPersistenceException

- the name of the persistence unitmap

also contain provider-specific properties. The
