DEFAULT_PERSISTENCE_UNIT_CWOBJ3112I=CWOBJ3112I: A JPA persistence unit name was not specified. The first persistence unit {0} defined in the persistence.xml is going to be the default persistence unit.
Explanation
The JPA persistence unit name was not provided to the method in the persistence.xml. By default, eXtreme Scale is going to use the first persistence unit defined in the persistence.xml.
User response
No action is required if the first persistence unit is acceptable. Otherwise, specify a persistence unit name when calling methods with the persistence unit name parameter (for example, ClienterLoader#Load).
