The library version 1.1.0 r88 is from the 1.0 series of the validation
framework which has different capabilities, limitations, and
instructions for use than the 2.0 features. The instructions and most
of the documentation have been updated to support the 2.0 release of
the framework. For example: "com.em.validation.Validation" is the 2.0
series. For use with the 1.0 series you would need to include the
java bean validation 1.0 source jar.
If you already have maven installed, building the 2.0 framework from
source is as simple as "maven clean compile install" and then you can
use it from your local repository.
Otherwise you'll probably want to try 2.0 preview revision 255. The
only thing it really lacks is class-level validation.
