Really Easy Validation
REV is a validation framework that allows you to write your validation rules once and then generate the code you need for the client (i.e. JavaScript) and the server (i.e. Java, Perl).
Status
REV is under active development. Check back soon for file releases - or feel free to access the subversion repository at https://svn.sourceforge.net/svnroot/rev-validation. You can also browse the repository at http://svn.sourceforge.net/rev-validation.
