OVal 1.80 Publishing Java Object Validation Framework

Oval is a practical extensible validation framework for various types of Java objects (but not for JavaBeans). Constraints can be configured with annotations, POJOs, or XML. Custom constraints can be expressed in pure Java or in scripting languages such as http://www.aliyun.com/zixun/aggregation/33906.html ">javascript,groovy, or BeanShell." In addition to simple object validation, oval can also provide certain programming of contract features that they can easily use to provide ASPECTJ aspects.

The OVal 1.80 version adds support for constraints that declare nested properties by constraining the new target attribute of the annotation. A high flush cache and a compiled mvel expression are added to compile ognl expressions.
