I am fairly new to JBoss and even moreso to the new EJB 3.0 spec. I recently I discovered that my database and its data will not survive the shutdown of the application server. When I restart my application server, the database comes back up but I loose all my data. Is this normal behaviour for JBoss or the persistence model? If not please help understand why I am getting this. I am using the new EJB 3.0 persistence model to code my entity beans and there is no existing database schema. Thanks for your support in advance.
