Arquivo Discussoes de Programacao e Tecnologia Quando eu coloco essa tag no persistence.xml
<provider>org.hibernate.ejb.HibernatePersistence</provider>
Da o seguinte erro quando vou subir a aplicação alguem sabe pq?
java.lang.ClassNotFoundException: org.hibernate.ejb.HibernatePersistence
Tenho todas as libs do hibernate em web-inf/lib
A classe em questão fica dentro da biblioteca do Hibernate EntityManager (no meu se chama hibernate-entitymanager-4.0.0.CR1.jar).
Onde você está fazendo deploy dessa aplicação? Tenha a certeza de que você está empacotando esse jar na sua aplicação.
Entao amigo eu uso Weblogic dentro do weblogic tenho meu EAR que contem um ProjetoWEB e nesse projeto estão os jars dentro de web-inf/lib
Esse é o único erro que aparece nos logs? Poderia enviar o trecho completo? ao invés de colar aqui, cole no pastebin.com e poste aqui o link gerado por ele.
