Olá possoal, tudo bem ? ? ? ?
Tô precisando de uma ajudinha de vocês que são mestres em desenvolvimento web com java.
Eu tenho uma aplicação rodando no tomcat e com banco oracle 10g.
Uso o hibernate 3 para persistencia e a implementação gerada pelo plugin hibernate syncronizer (eclipse).
O problema é que após algumas horas de inatividade, o sistema perde a conexão com o banco de dados.
Alguém já passou por isso. Quem poder me ajudar agradeço muito.
Abaixo a exceção:
