OVal (Object Validation Framework) is a validation framework for Java objects

Per the OVal about page:

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.
