• The following code is used to create the entity manager given a persistence unit name and a data source name:

    private static EntityManagerFactory buildEntityManagerFactory(String aInPersistenceUnit, String aInDataSource)
    {
        Map<String, String> lConfigOverrides = new HashMap<>();
        lConfigOverrides.put("javax.persistence.transactionType", PersistenceUnitTransactionType.RESOURCE_LOCAL.name());
        if (aInDataSource != null)
        {
            lConfigOverrides.put("javax.persistence.nonJtaDataSource", aInDataSource);
            lConfigOverrides.put("javax.persistence.jtaDataSource", aInDataSource);
        }
        return Persistence.createEntityManagerFactory(aInPersistenceUnit, lConfigOverrides);
    }
