Erro ao criar Entity Manager Factory!

[guilherme_82]

Fala galera,

seguinte, ao acessar o metodo Persistence.createEntityManagerFactory("sistemabancario");
recebo a exceção:
java.lang.ClassCastException: org.hibernate.ejb.HibernatePersistence

O que seria??

Oh, sorry, I wrote in Portuguese!

When I execute the method Persistence.createEntityManagerFactory("sistemabancario");

I got the exception:

java.lang.ClassCastException: org.hibernate.ejb.HibernatePersistence

Anyone knows what's happening?

Thnaks, Guilherme
