Galera.. bom dia
Estou trabalhando com uma aplicação desktop e pretendo persistir informações (local) utilizando o Derby DB
Estou utilizando JPA e Hibernate como frameworks para ORM. É a primeira vez que faço uso de Hibernate e estou com dificuldades em entender o erro que estou enfrentando... Alguém consegue me dar uma mão
Sempre que tento fazer qualquer operação de CRUD a resposta é A tabela/visão 'CLIENTE' não existeDesde já, obrigado
