AULA 2 - Exercio Caelum com erro.

Oi Thiago,

Repare a mensagem "Could not find any META-INF/persistence.xml".

O JPA/Hibernate não encontrou o persistence.xml e consequentemente gerou uma exceção.

O arquivo persistence.xml deve estar dentro da pasta META-INF do seu classpath (no Eclipse dentro da pasta src).

Realizei a alteração. Ao rodar o projeto, verifico no mysql que a tabela foi criada. Entretanto, não existe nenhum dado contido na tabela. O código gerado na saída do eclipse é:Out 05, 2013 12:20:45 PM org.hibernate.annotations.common.Version <clinit> INFO: HCANN000001: Hibernate Commons Annotations {4.0.1.Final} Out 05, 2013 12:20:45 PM org.hibernate.Version logVersion INFO: HHH000412: Hibernate Core {4.2.0.Final} Out 05, 2013 12:20:45 PM org.hibernate.cfg.Environment <clinit> INFO: HHH000206: hibernate.properties not found Out 05, 2013 12:20:45 PM org.hibernate.cfg.Environment buildBytecodeProvider INFO: HHH000021: Bytecode provider name : javassist Out 05, 2013 12:20:46 PM org.hibernate.service.jdbc.connections.internal.DriverManagerConnectionProviderImpl configure INFO: HHH000402: Using Hibernate built-in connection pool (not for production use!)

Detalhe: Utilizo o Mysql versão 6

Oi Thiago, como falei no outro post, para usar MySql 6 você precisa atualizar o driver JDBC. Eu não encontrei esse JAR como download e aconselho usar MySQL 5.
