I am using Jersey/JAX-RS via DropWizard 0.7.1 to expose RESTful service endpoints. I have all of my entity POJOs annotated with both JAX-RS and Hibernate/JSR-303 bean valida
Add @Valid before @PathParam to validate with Jersey.
@Valid
@PathParam
See https://jersey.java.net/documentation/latest/bean-validation.html#d0e12201
You may have to do some configuration.
