Why does <f: validateBean / "> not work?

I am using JSF 2.0, hibernate-validator4.2.jar validation-api.jar tomcat and Eclipse.

I posted the annotation @Size(min=3, message="xxx")in @ManagedBean and <f:validateBean />between<h:inputText value="#{user.name}"></h:inputText>

When I try to start a project, I get this error ...

exception

javax.servlet.ServletException: Expression Error: Named Object: javax.faces.Bean not found.
    javax.faces.webapp.FacesServlet.service(FacesServlet.java:606)

root cause

javax.faces.FacesException: Expression Error: Named Object: javax.faces.Bean not found.
    com.sun.faces.application.ApplicationImpl.createValidator(ApplicationImpl.java:1593)
    com.sun.faces.facelets.tag.jsf.ValidatorTagHandlerDelegateImpl.createValidator(ValidatorTagHandlerDelegateImpl.java:244)
    com.sun.faces.facelets.tag.jsf.ValidatorTagHandlerDelegateImpl.applyAttachedObject(ValidatorTagHandlerDelegateImpl.java:132)
    com.sun.faces.facelets.tag.jsf.ValidatorTagHandlerDelegateImpl.applyNested(ValidatorTagHandlerDelegateImpl.java:211)
    com.sun.faces.facelets.tag.jsf.ValidatorTagHandlerDelegateImpl.apply(ValidatorTagHandlerDelegateImpl.java:87)
    javax.faces.view.facelets.DelegatingMetaTagHandler.apply(DelegatingMetaTagHandler.java:120)
    javax.faces.view.facelets.DelegatingMetaTagHandler.applyNextHandler(DelegatingMetaTagHandler.java:137)

why? (this appears only when the tag is set)

User.java

import java.io.Serializable;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.validation.constraints.Size;

@ManagedBean(name="user")
@SessionScoped
public class User{
    @Size(min=3, message="At least 3 characters!")
    private String name;


    public String getName() {
        return nume;
    }
        public void setName(String name){
                this.name=name;
    }

}
