OVal - the object validation framework for Java 5 or later Version $VERSION$ http://oval.sf.net 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. Besides field/property validation OVal implements Programming by Contract features by utilizing AspectJ based aspects. This for example allows runtime validation of method arguments. =========================================== Portions created by Sebastian Thomschke are copyright (c) 2005-2016 Sebastian Thomschke.
