Is it possible to change the name and location of the ValidationMessages.properties file? By default, it should be inside the classes directory of the war file (root of the classpath).
I am using Hibernate Validator and RestEasy as my JavaBean Validation and JAX-RS providers.
You can override the MessageInterpolator defined in the configuration and pass it a different resource bundle locator.
We have everything explained in this section of the reference documentation.
