Criei um Projeto EJB, e uma classe... Na hora do deploy me mostra esse erro logo abaixo. Está faltando importar algum jar? os que eu tenho são esses: antlr, dom4j, hibernate-commons-annotations, hibernate-core, hibernate-entitymanager, hibernate-jpa, jandex, javassist, jboss-logging, jboss-loging-annotations, jboss-transaction-api e estão dentro do 'EarContent/lib'.

Estou usando o glassfish, ele cria as tabelas no mysql corretamente, mas depois me retorna nulo.
