Welcome to JaValid
JaValid is an open source framework for validating your Java business objects. JaValid is licensed under the Eclipse Public License 1.0. JaValid 1.2 is the latest release.
JaValid is an annotation-based validation framework, which allows you to annotate your Java objects to introduce validation. JaValid can be used in any type of Java application (standalone application, web application etc). The framework currently provides full integration with the Spring Framework, Java Server Faces, Facelets, and any database. The framework can be extended easily, by means of extensions, and also allows you to add your own validation constraints in addition to the ones shipping with the framework.
The framework is documented well (both the source and the general documentation), so check it out. To learn more, have a look on the documentation page.
The source and distributions are hosted on sourceforge, go to the downloads directly here. You may also want to check out the weblog, which contains some useful information, including several examples.
Have fun using JaValid!
This is an early implementation of JSR 303 (Bean Validation), a specification of the Java API for JavaBean validation in Java EE and Java SE.
The technical objective is to provide a class level constraint declaration and validation facility for the Java application developer, as well as a constraint metadata repository and query API.
This implementation is based on the validation framework of agimatec GmbH, that is in production for more than a year and offers additional features, like XML-based extensible metadata, code generation (JSON for AJAX applications), JSR303 annotation support.

iScreen is a Java Object Validation Framework, suitable for validating Java Objects (including JavaBeans) to ensure that they are "valid" according to some definition (usually via configuration). The term 'iScreen' means "information screen," where 'screen' means to protect or conceal. Information, represented by Java objects, are passed through the screen. If they are considered acceptable (i.e. valid), then nothing occurs. If not, then an exception is thrown, allowing the application to notify someone or something of the invalid information.
OVal is a generic validation framework for any kind of Java objects (not only JavaBeans) and allows you:
*
to specify constraints for class fields and method return values
*
to easily validate objects on demand
*
to specify constraints for constructor parameters that are automatically checked when the constructor is called
*
to specify constraints for method parameters that are automatically checked when the method is called
*
to enforce full object validation after an object instance has been created
*
to enforce full object validation before a method of the object is called
*
to enforce full object validation after a method of the object is called
to either let OVal throw constraint violation exceptions during automatic checks or alternatively notify constraint violation listeners.
*
to easily create custom constraints
