Hello everyone, where can I find documentation to how to configure jpa hoernate persistence? I use toplink as provider, but since a friend told me that hibernate is provider and pool, it got my attention. If someone can help me configuring it or providing me some documentation I would appreciate it. And already post a future doubt here to, every night when there's no activity in the system, the connection get broken and we have to restart all instances of tomcat, that happens because the system gets an iddle time of 5 ~ 11 hours, does hibernate solves this problem?
