OpenXava is a framework for Rapid Java Web Development, well-suited for business and database oriented applications.
OpenXava allows you develop applications just by writing simple domain classes with Java or Groovy. The user interface is generated automatically in runtime, without code generation.
OpenXava 4.4 has some new interesting features such as:

  • Totals, row count and add action in the collection frame when the collection is folded.
  • The frames are folded using a slide effect.
  • It's possible to filter by range in list and collections.
  • Support for Java 7.

And some other useful new features and bug fixes.
