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 4.5.1 发布，主要改进记录包括：
Focus order only includes editors. Actions, links, tabs, etc. are excluded.
SimpleHTMLReportAction extends SimpleTemplaterAction to be able to use SimpleTemplater in email messages.
Documentation for @Tree is improved.
Focus is not set in the first load of detail only modules.
Navigating among objects with references with inheritance no longer produces a system error.
New in a model with a reference with inheritance does not reset the reference view to the base model.
Searching from a reference with inheritance did not always show all the objects of the hierarchy.
There are many more bugfixes
