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.
Since OpenXava 3.0 you can 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 (OX2 generated code from XML definitions).
What's new in 3.0?
- POJOs + Java 5 annotations for defining business components.
- XavaException now is a RuntimeException.
- MapFacade methods do not longer throws RemoteException, instead it now throws SystemException (runtime).
- Fix: JasperReport generation: Invalid encoding name "Cp1252" on some windows, and malformed URL on WebSphere 6.0.
- Fix: Fails on WebSphere 6.0 (at some level patch). Broken since 2.2.3.

Hi Carlos,
Hibernate and OpenXava are two very different things.
OpenXava allows you to obtain a complete application with user interface and behaviour included,
while Hibernate is a persistence engine.
OpenXava uses Hibernate JPA implementation for persistence.
Cheers

Javier,
For UI with lots of properties coming from one entity instead of putting all the components into 1 screen, we usually develop UI with wizard style, does OpenXava support generating this kind of UI ?
Also, from security point of view, suppose I want to restrict certain user from adding new record but allow him/her to update existing ones. How/where can I put this kind of logic ?
Regards,
Setya

Hi Setya,
Maybe the sections (displayed as tabs) can be useful for you case, look at:
http://openxava.wikispaces.com/view_en#toc3
Define two modules one for full CRUD and other for only update. This generated two portlets, then assign each portlet to the user, group or roles you want using the portal admin tools.
Look at

When you try to implement it go to the OX forum and sure the OX community helps you

HI,
I downloaded the openxava into Ubuntu and tried to run the startup.sh BY CLICKING ITbut couldn't see any results in the browser.
How do you actually start it in Ubuntu Linux? i DON'T KNOW THE COMMAND!
i downloaded it into Windows Vista, but it seems to only download the tomcat portion. Ia there a way to downloadcorrectly?
Thanks
