In today’s post we are going to open our mind, step away from traditional Java EE / Java SE JPA-based stack (which I think is great) and take a refreshing look on how to access database in your Java applications using the new kid on the block: Slick 2.1 from Typesafe. So if JPA is so great, why bother? Well, sometimes you need to do very simple things and there is no need to bring the complete, well modeled persistence layer for that. In here Slick shines.

EJB 3.1 introduced timeout related annotations as a part of its API.

  • @AccessTimeout
  • @StatefulTimeout

Let’s quickly look at what they are and why are they important
