Java Enterprise Applications from Model

 

OpenXava is a productive way for creating Enterprise Applications with Java. Indeed, it's faster developing with OpenXava than with Ruby On Rails, Spring MVC, or any other MVC framework. This is because in OpenXava you only have to write the Model. The Controllers are reused, and the View are generated automatically. We can say that OpenXava is a Mc framework.

 

OpenXava is a JPA Application Engine. You put your JPA classes and, in exchange,  you will obtain a full featured application ready for production, and without code generation. See it vividly at MySchool demo.

 

OpenXava has been created by Java developers (who need developing Java Enterprise applications in a productive way)  for their own use; hence it's powerful, extensible and enjoyable by a Java expert. In the other hand OpenXava allows to a new Java developer to start rapidly to be productive, therefore is a pleasant experience for beginners too.

The better way to learn about OpenXava is downloading it, and following the tutorial.

Don't hesitate to ask in the the community forum any question you have.

2008-3-5: Version 3.0 released

Download - Change log

OpenXava 3.0 allows you to define components using POJOs + annotations, as alternative to XML. The advantages are:

  • You can take your application developed using POJOs and JPA and convert it in an OpenXava application in a few minutes.
  • You can use standard tools for POJO/EJB3 to develop OpenXava applications. Tools as UML tools, Dali for mapping, Hibernate tools for importing database schemas to EJB3 POJOs, etc.
  • You do not need code generation any more.
  • You can develop using Java.

Of course, OpenXava 3.0 is backward compatible with 2.0 and 1.0 (it still supports XML and code generation) , therefore you can update your current OpenXava applications to this new version without rewrite your code and although you do not use JPA or POJOs.
