GWT-Platform login + session management

阅读更多关于 GWT-Platform login + session management

I am new to gwt and I am creating a login page using gwt and I need help with session managment. All answers already given here, explains how to manage sessions on server side, I need to use session on client side (browser's session) exactly like with JSP files: session.setAttribute("UserName", username); Can any one provide a clear full example of how to implement this (Remember I am new to gwt). I looked at this tutorial: http://code.google.com/p/google-web-toolkit-incubator/wiki/LoginSecurityFAQ And this doesn't help me because it doesn't explain how to use the browser's session. Thank you.
