Pessoal, estou acompanhando o livro de springMVC da casa do código e estou tendo problemas ao tentar cadastrar produtos. Ao clicar em enviar é gerado um erro: HTTP Status 500 - Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JPA EntityManager for transaction; nested exception is javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: Could not open connection
Já pesquisei e não estou conseguindo corrigir este erro.
Percebi que o BD não está sendo criado.
Será que vocês poderiam me ajudar?
