Parameters:

locations - the comma-separated list of potential persistence XML file locations.

setPersistenceXmlLocations

public void setPersistenceXmlLocations(java.lang.String... persistenceXmlLocations)

Accept a list of locations for persistence XML files. Before passing this list to our superclass DefaultPersistenceUnitManager, check each location on the list for actual existence.
