Spring MVC 3 Validation – Unable to find a default provider

If you are using Maven, you must add a dependency to the Hibernate Validator Annotation Processor.

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-validator-annotation-processor</artifactId>
  <version>4.1.0.Final</version>
</dependency>

You can find it in the JBoss repository :

<repository>
  <id>JBoss Repository</id>
  <url>https://repository.jboss.org/nexus/content/repositories/releases</url>
  <name>JBoss Repository</name>
