& lt ;? xml version = "1.0" encoding = "UTF-8" ? & gt ;
& lt ; persistence version = "2.0" xmlns = "http://java.sun.com/xml/ns/persistence" xmlns : xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi : schemaLocation = "http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" & gt ;
& lt ; persistence - unit name = "ssPU" transaction - type = "RESOURCE_LOCAL" & gt ;
