Display message login fail JSF
<h:form> 

    <h1>Login</h1>
    <!--Message ManagedBean-->
    <h:messages globalOnly="true" styleClass="message_loginfail" />

    <!--Message Input-->
    <h:message for="user" style="color: red"/>
    <h:inputText id="user" value="#{loginManagedBean.username}" required="true" requiredMessage="Please Enter your username" pt:placeholder=" Enter your username"/>

    <!--Massage Input-->
    <h:message for="pass" style="color: red"/>
    <h:inputSecret id="pass" value="#{loginManagedBean.password}" required="true" requiredMessage="Please Enter your username" pt:placeholder=" Enter your password"/>

    <h:commandButton styleClass="button" action="#{loginManagedBean.login() }" value="Login"/> 

</h:form>
Kiến thức cần có:
1,   <h:message/> là hiển thị lỗi từ input được for="id"
2,   <h:messages/> 
    * Display =>> <h:message/> + ManagedBean
    * globalOnly="true" Display =>> ManagedBean

Cách viết style cho JSF: 

Markup
<div class="buttons">
    <h:commandButton value="Button Text" styleClass="apply"/>
    <h:commandButton value="Button Text" styleClass="cross"/>
</div>

CSS

.buttons .apply {
    background: #eee url(path/to/apply.png) no-repeat 0 50%;
} 

.buttons .cross {
    background: #eee url(path/to/cross.png) no-repeat 0 50%;
}

public String login() throws SQLException {
        UserDAO udao = new UserDAO();
        if (udao.checkLogin(username, password)) {
            FacesContext facesContext = FacesContext.getCurrentInstance();

            fc.addMessage(null, new FacesMessage("Sai username hoặc password!"));
            return null;
        }
    }

public void logout() throws IOException {

        ec.invalidateSession();
        ec.redirect(ec.getRequestContextPath() + "/faces/login.xhtml");
