ValidationException: Unable to find a default provider

Question

I found three entries for this in stack overflow:

javax.validation.ValidationException: Unable to find default provider

javax.validation.ValidationException: Unable to find a default provider

Spring MVC 3 Validation - Unable to find a default provider

and all three say to add hibernate validator to the class path. What do I do when I've done that and still get the same error?

Answer 1

Add hibernate-validator dependency which has implementation of JSR 303 (bean validation).

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>4.2.0.Final</version>
</dependency>
