OpenXava 3.1.4 is a framework focused in productivity for developing business Java applications. The idea is that you write only your POJOs annotated with JPA and you get an application ready for production.

With OpenXava, you only need to write your model, POJOs and Java annotations. You do not need to write the view, and the controller (for CRUD, printing, etc) is reused. And from that you'll have an application for CRUD, report generation in PDF, export to Excel, searching, sorting, validations etc. You only need to write a simple Java class, no XMLs, no JSPs and no code generation.

Look at the demos.

If you current applications use JPA entities, you can move your JPA code to an OpenXava application and obtain an AJAX portal application easily.

OpenXava is not only for writing simple CRUDs for simple classes, you can create sophisticated applications with complex logic and advanced UI. OpenXava supports references, collections, inheritance, nested tabs, nested frames for grouping, etc.

If you develop business applications, use JPA or are interested in Java Portals (as Liferay, WebSphere Portal or JetSpeed) do not doubt, download OpenXava and evaluate it.

This new 3.1.4 version has more than 50 new features and fixes over 3.1.3, including translation to Serbian and Swedish, support for Liferay 5.2.3, @Formula annotation, formatters for list mode, etc.

OpenXava is LGPL so you can develop commercial applications with it.
