Spring JSR-303 bean validation not working, empty bindingresult

Hi StackOverflow

I have tried to add beanvalidation to my small webapplication. Until now it doesn't work because my bindingresult stays empty. I have done the following:

• Add all dependencies (Classmate, Javax.el, Jboss-logging, Validation-api)


• Added annotations


• Updated controller with @valid and BindingResult


• Updated my jsp page


• Maked sure I have <mvc:annotation-driven/> in my dispatcher-servlet.xml

I have looked at similar questions here on stackoverflow, yet I have not been able to find the answer I need. I'm using Apache Tomcat.

My controller:

@RequestMapping(value = {"/cardForm"}, method = POST, params = {"dispatcher=createCard"})
    public String addCard(@Valid @ModelAttribute("card") Card card, BindingResult result) {
        System.out.println(result.getErrorCount());
        if (result.hasErrors()) {
            return "cardForm";
        } else {
            try {
                service.addCard(card);
            } catch (MapperException ex) {
                Logger.getLogger(CardController.class.getName()).log(Level.SEVERE, null, ex);
            }
            return "redirect:/";
        }
    }

My class to be validated:

    }

    public void setText(String text) {
        this.text = text;
    }

    public String getPlayerClass() {
        return playerClass;
    }

    public void setPlayerClass(String playerClass) {
        this.playerClass = playerClass;
    }

        return cost;
    }

    public void setCost(int cost) throws DomainException {
        this.cost = cost;
