I am developing a
struts based application on google app engine. I am using google's user service to allow users to log into my application.
When the user is signed into his google account and opens my application, my application must not ask to sign in again. Suppose the homepage of my application is index.jsp, it should say
Welcome user
xyz@gmail.com
To do so, I have to check whether there is a current user or not like this
But I am not supposed to use scriptlets in my application. I have to achieve this using struts tags.
Any help is greatly appreciated. Thank you all in advance and good day.
