  package com.tutoraspire;  import javax.faces.application.FacesMessage;  import javax.faces.bean.ManagedBean;  import javax.faces.context.FacesContext;  @ManagedBean  public class Growl {  private String username;  private String password;  public String getUsername() {  return username;  }  public void setUsername(String username) {  this.username = username;  }  public String getPassword() {  return password;  }  public void setPassword(String password) {  this.password = password;  }  public void displayMessage() {  FacesContext context = FacesContext.getCurrentInstance();  context.addMessage(null, new FacesMessage(“Login Successfuly”, “Welcome: ” + username));  }  }
