The Bean Validation 1.1 specification provides an annotation based model for validating JavaBeans. It can be used to assert and maintain the integrity of data as it travels through an application. This feature is built on top of Apache BVal.
To enable the Bean Validation 1.1 feature, add the following element declaration inside the featureManager element in your server.xml file:
<feature>beanValidation-1.1</feature>
If you are developing a feature that depends on the Bean Validation 1.1 feature, include the following item in the Subsystem-Content header in the feature manifest file for your new feature:
com.ibm.websphere.appserver.beanValidation-1.1; type="osgi.subsystem.feature"
