OpenXava 4.1: Open Source tool for Rapid Web Development with Java

Feb. 16, 2011 - PRLog -- OpenXava is a framework for rapid development of business applications using Java or Groovy. It is easy to learn and one can have an application up in no time. At the same time, OpenXava is extensible, customizable and the application code is structured in a very pure object oriented way, allowing you to develop arbitrarily complex applications.
The OpenXava approach for rapid development differs from those that use visual environments (like Visual Basic or Delphi) or scripting (like PHP). Instead, OpenXava uses a model-driven development approach, where the core of your application are Java classes that model your problem. This means you can stay productive while still maintaining a high level of encapsulation.

The new version of OpenXava, OpenXava 4.1, adds support for JSR-303, the Java standard for validation. Moreover, it contains some interesting features in the list and the collections user interface.

The support of Bean Validation standard (JSR-303), together with the already supported JPA 2.0 (JSR-317) and  Dependency Injection (JSR-330) standards, allows you to move your JBoss Seam or Spring application code (at least the entities) to OpenXava in order to obtain a Rich AJAX application from you already existing code in no time.
