How to show h:message based on condition? - jsf

Question

I am making multi-language website where I am using Validator for one field.
After validation, I receive response as err002, err003 and based on this error I would be showing the respective error in message format. So what I was planning is something like below.
What I have is <h:message for="password">
What I wanted to do is as below.
if (message is err002) {
show message of err002 from the properties file.
#{msg['err002']}
}
if (message is err003) {
show message of err003 from the properties file.
#{msg['err003']}
}
Any idea how to get this done?
Actually what I want to do is display error message in both language. What I have is language code in session bean, but I can't check language code in validators.
Any idea/ suggestion how this can be done would be greatful.

public class LanguageBean implements Serializable {
Properties files that I have are

You can easily achive it in a validator method. Use it like
#FacesValidator("passwordValidator")
public class PasswordValidator implements Validator {
String err1, err2, err3;
public PasswordValidator() {
ResourceBundle bundle = ResourceBundle.getBundle("msg", FacesContext.getCurrentInstance().getViewRoot().getLocale());
err1 = bundle.getString("err1");
err2 = bundle.getString("err2");
err3 = bundle.getString("err3");
}
public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
String pass = (String) value;
FacesMessage msg;
if(/*some condition*/) {
msg = new FacesMessage(err1);
} else if(/*other condition*/) {
msg = new FacesMessage(err2);
} else {
msg = new FacesMessage(err3);
}
if(msg != null) {
throw new ValidatorException(msg);
}
}
}
And use it in view with
<h:inputText id="password" validator="passwordValidator" .../>
<h:message for=password .../>
