PersistenceContext = Cannot parse persistence unit from class path resource [META-INF/persistence.xml]

Estou tentando deixar o Spring tomar conta das transações pelo entityManagerFactory, temos spring-context configurado, persistence.xml na pasta META-INF do class path. o fato é que um erro ocorre PersistenceContext = Cannot parse persistence unit from class path resource [META-INF/persistence.xml]

Se alguém puder me ajudar agradeço
