Vaadin Project woking properly in Firefox but not in Google Chrome

Hai sir,

          My vaadin project  is working properly  both  in  [b]

[/b] and
Google chrome
browsers while running through
Eclipse IDE
. After exporting the war file from Eclipse ,it runs in
Firefox ,but not working properly in Google Chrome browser. The problem is that in both browsers login form is opened properly .While clicking the login button
Firefox opens the Home page .In
google chrome
it tried to load the page but again it comes into the login page . I am using Google chrome Version 22.0.1229.92.
I used three add-on in my project . Paperstack, Refresher, Confirm Dialog .

Please give some solution to fix it.

Thank you all.
