which server you are using?
The error that you have mentioned is during undeployment. It might be possible that first your server undeploy the application and deploying it again to reflect the changes and during undeployment you are getting the error.
If you have deployed your application with login page,same procedure should be used to deploy it again. Try with fresh deployment.
