I am working on one application. It is using j_security_check to authenticat user. It is working fine. It authenticat user. if login is not successful I want to display login failure page . For this i am using

<login-config>
       <auth-method>FORM</auth-method>
       <form-login-config>
            <form-login-page>/webpages/login.jsf</form-login-page>
            <form-error-page>/webpages/loginerror.jsf</form-error-page>
       </form-login-config>
</login-config>
