Presentation from the last server forum - REST

Thanks to all participants for the interest and the challenging questions. The slides are in the attachment. Here are answers to the questions I could not answer on forum:

* Spring and JAX-RS - my mistake, Spring does not have it's own implementation. What I saw when I listed it, were different REST solutions implemented with Spring MVC. But such solution is similar to REST with servlets, it's not an implementation of JAX-RS.

* DataSource entity type - it's not related to database, it's javax.activation.DataSource
