Removing session from Vaadin Application

Hi , I have a Vaddin application and i want to remove session time out from my application. As of now i am setting session configuration in my application web.xml to the max of 30 minutes. Can anyone please help me out . Thanks.

You can use the SessionGuard addon which you can get

Or SmartSession from

They both have a mode to keep sessions alive.
