The most recent version of hibernate-validator does not contain the class org.hibernate.validator.engine.ResourceBundleMessageInterpolator anymore, so an Exception is thrown.

using an older hibernate-validator 4.0.2 solves the problem.

regards, markus

look like the classe change to a new package

org.hibernate.validator.messageinterpolation.ResourceBundleMessageInterpolator

I changed the source code to that : interpolator = new ResourceBundleMessageInterpolator();

but I have a problem later.

In struts.xml I have this

    <interceptors>
        <interceptor-stack name="mybasicStack">
            <interceptor-ref name="paramsPrepareParamsStack"/>
            <interceptor-ref name="defaultStackHibernate"/>
        </interceptor-stack>
    </interceptors>

    <!-- Default interceptor stack. -->
    <default-interceptor-ref name="mybasicStack"/>

in my DAO

public String execute() throws Exception {

    try {
        service.create(user);
    } catch (Exception e) {
        e.printStackTrace();
        throw e; 
    }
    return SUCCESS;
}

if I run the code in debug mode.. I see that I go into : Struts2HibernateValidatorV402.java before I go into my execute method.

but the validator never return errors.

band I will get this error

messageTemplate='{javax.validation.constraints.NotNull.message}'} ]

File: org/hibernate/cfg/beanvalidation/BeanValidationEventListener.java Line number: 161

this line : Set> constraintViolations = validator.validate(actionAs);

in Struts2HibernateValidatorV402.java

return a empty Set.

I am facing the same problem. I also need the hibernate-validator 4.1.0.

I created a Injector to validate Model using Hibernate validator 4.1. Works fine for me. I'll create a project on github soon. I didn't need all the others extras of this plugin.

In my project I only need the hibernate validation.
