Spring MVC with Hibernate Validator. How to validate property by group?

There are two problems:

1.Sping/MVC use hibernate validater, Custom validater how to show message? like: Cross field validation with Hibernate Validator (JSR 303)

@FieldMatch.List({
    @FieldMatch(fieldName="password",verifyName="passwordVerify",message="password confirm valid!", groups={Default.class})
})
@ScriptAssert(lang="javascript",script="_this.name.equals(_this.verifyCode)")
public class LoginForm {...}

How to show the message in jsp with resource property file?

NotEmpty.loginForm.name="username can not be empty!" NotEmpty.loginForm.password="password can not be empty!"

2. I want to use group validater with spring mvc, like one userform for login and register

    @FieldMatch.List({
    @FieldMatch(fieldName="password",verifyName="passwordVerify",message="password confirm valid!", groups={Default.class})
})@ScriptAssert(lang="javascript",script="_this.name.equals(_this.verifyCode)",groups={Default.class,LoginChecks.class,RegisterChecks.class})
public class LoginForm {
    @NotEmpty(groups={Default.class,LoginChecks.class,RegisterChecks.class})
    @Size(min=3,max=10,groups={LoginChecks.class,RegisterChecks.class})
    private String name;

    @NotEmpty(groups={Default.class,LoginChecks.class,RegisterChecks.class})
    @Size(max=16,min=5,groups={LoginChecks.class,RegisterChecks.class})
    private String password;

    private String passwordVerify;

    @Email(groups={Default.class,LoginChecks.class,RegisterChecks.class})
    private String email;

    private String emailVerify;
...
}

Controller parameter annotation is @valid, any annotation support group validater by group?
