Method Detail

getPersistenceUnitInfo

javax.persistence.spi.PersistenceUnitInfo getPersistenceUnitInfo()

Returns:

A PersistenceUnitInfo that can be used to create an EntityManagerFactory

getContainerProperties

java.util.Map<java.lang.String,java.lang.Object> getContainerProperties()

Get a Map of continer properties to pass to the PersistenceProvider when creating an EntityManagerFactory.

Returns:

A Map of properties, or null if no properties are needed.

registered

void registered()
