title: Simple ways to keep data on redeployment of Java EE 7 web application
body: <p>My Java EE 7 web service generates statistics once per day, and because data is stored only in an ApplicationScoped bean, it does not survive redeployment, so clients cannot retrieve statistics until the next run completed.</p>
  
  <p>Does Java EE 7 provide a simple way to keep application state so that it will be available after redeployment, similar to an in-memory database? As it is only one big object (list), I would prefer something simpler (and maybe better performing too) than a database.</p>
