Baritus is an extension of the mature web MVC framework Maverick. Maverick is a minimalist framework which focuses solely on MVC (model 2) logic, allowing you to generate presentation using a variety of templating and transformation technologies. Read more about Maverick here.
Baritus is an easy to use yet flexible framework that focuses on fine-grained bean population and validation from HTTP request parameters. Furthermore, Baritus gives you an alternative to frameworks that focus on using XML configuration. Instead, Baritus gives ready-to-use defaults (like using introspection for conversion), and lets you use Java to configure validation, population and ways to extend or override the default behaviour.
Baritus builds on Maverick, but does not alter it. Baritus provides a base class, nl.openedge.baritus.FormBeanCtrl that is modeled after org.infohazard.maverick.ctl.FormBeanUser from the Maverick project. Like FormBeanUser, instances of FormBeanCtrl are singletons (allthough by extending from FormBeanCtrlBase you can use single-use controllers) and use seperate JavaBeans for population.
