[OmniFaces utilities 2.0] Bean Validation - bootstrap the Validation using the default validation provider resolver


[OmniFaces utilities] The getBeanValidatorFactory() bootstraps the Validation using the default validation provider resolver.

Method:
Usage:

Those who are familiar with Bean Validation and implicitly with javax.validation.Validation, knows that there are three ways to bootstrap the Validation:

·         using the Validation#buildDefaultValidatorFactory()
·         choosing a custom ValidationProviderResolver
·         specifying explicitly and in a type safe fashion the expected provider

As you can see from the source code listed above, OmniFaces uses the first approach. So, whenever you need to bootstrap the javax.validation.Validation via the Validation#buildDefaultValidatorFactory(), you can use the OmniFaces shortcut, getBeanValidatorFactory() as below:

import org.omnifaces.util.Platform;
import javax.validation.ValidatorFactory;
...
ValidationFactory validationFactory = Platform.getBeanValidatorFactory();
