This package is a copy of the Bean Validation API classes from the Agimatec Validation Project. http://agimatec-validation.googlecode.com/svn/trunk/src/main/java/javax/validation
Changes made for GWT compatibility :
Please note the @Pattern annotation support is limited to compatibility between Java and JavaScript regular expression, as explained here.
You can import the javax.validation emulated classes by adding the following import to your .gwt.xml file:
<inherits name="com.googlecode.gwtx.javax.Persistence"/>
