The Envers module aims to enable easy auditing/versioning of persistent classes. All that you have to do is annotate your persistent class or some of its properties, that you want to audit, with @Audited. For each audited entity, a table will be created, which will hold the history of changes made to the entity. You can then retrieve and query historical data without much effort.
Apache Struts is a free, open-source, MVC framework for creating elegant, modern Java web applications. It favors convention over configuration, is extensible using a plugin architecture, and ships with plugins to support REST, AJAX and JSON.
Bootzooka is a simple application scaffolding project to allow quick start of development for modern, web based applications. If you'd like to have a jump start developing a Scala-based Single Page Application project, skipping the boring parts and focusing on the real business value, this template might be for you!
Bootzooka contains only the very basic features, that almost any application needs (listed below). These features are fully implemented both on server- and client- side. We hope that the implementations can also serve as blueprints for new functionalities.
akka-http is an Akka module, originating from spray.io, for building reactive REST services with an elegant DSL.

akka-http-session provides directives for client-side session management in web and mobile applications, using cookies or custom headers + local storage, with optional Json Web Tokens format support.
