OpenXava 3.1.4: Open Source Framework to Develop WebSphere Portal Applications
— OpenXava 3.1.4 is an open source framework to rapid development of Portlet Enterprise applications deployable in WebSphere Portal 6.1.

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.
