OpenXava是一个让使用XML与Java来开发J2EE商业应用程序变得简单的框架.OpenXava不使用常见的MVC架构，它是一个JPA应用程序引擎，你能够通过JDK5.0注解或XML描述对象-关系表的映射关系，并将运行期实体对象持久化到数据库中去。
使用OpenXava你只需要写model，POJOs，和Java 5 annotations，你不用写view，也不用写controller。
OpenXava 4.9 发布了，改进内容包括：
List mode was improved with better behavior, new filter options, and some style improvements.
PDF reports were adjusted, and most automatic reports are now ready to be used.
'My reports' has more options and is easier to use.
You can now use your OpenXava application as a reporting tool.
There were many other improvements and bugfixes
