JSF的入门,主要是讲的JSF的标签运用

package org.jsfeimhe.web.bean;

import java.util.Locale;
import java.util.ResourceBundle;

import javax.faces.application.Application;
import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.validator.Validator;
import javax.faces.validator.ValidatorException;

public class PasswordValidator implements Validator {

	public void validate(FacesContext facesContext, UIComponent uicomponent, Object passwordobj)
			throws ValidatorException {
		// TODO Auto-generated method stub
       String password=(String)passwordobj;
       if(password.length()<6){
    	   Application application=facesContext.getApplication();
    	   String messageFileName=application.getMessageBundle();
    	   Locale locale=facesContext.getViewRoot().getLocale();
    	   ResourceBundle  resourceBundle=ResourceBundle.getBundle(messageFileName,locale);
    	   String passwordValidatorError=resourceBundle.getString("PassworValidator");
    	   FacesMessage errorMessage=new FacesMessage(FacesMessage.SEVERITY_ERROR,passwordValidatorError,passwordValidatorError);
           throw new ValidatorException(errorMessage);
       }
	}
