Overview

OVal is a pragmatic and extensible validation framework for any kind of Java objects (not only JavaBeans). Constraints can be declared with annotations (@NotNull, @MaxLength), POJOs or XML.Custom constraints can be expressed as custom Java classes or by using scripting languages such as JavaScript, Groovy, BeanShell, OGNL or MVEL.
