map - 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.

Returns:

EntityManagerFactory for the persistence unit, or null if the provider is not the right provider

createEntityManagerFactory

protected EntityManagerFactory createEntityManagerFactory(java.lang.String emName,

classLoader - The classloader to search for persistence units on

Returns:

EntityManagerFactory for the persistence unit, or null if the provider is not the right provider
