ClassNotFoundException: javax.validation.ValidatorFactory

Question

I am trying to run a Spring MVC application in my local machine through Tomcat, but I am seeing:

NoClassDefFoundError: javax/validation/ValidatorFactory
         


        

Answer 1

You have the necessary jar file you need in hibernate-validator. This jar includes the javax.validation.ValidatorFactoryvalidation-api. So if you are including validation-api explicitly, you might have dependency conflicts. If not, you might just be having class reloading issues. Try cleaning your tomcat and restarting your IDE.
