I tried to use your solution (UI.getCurrent() ), but the result is still empty.
Maybe it is because the onRequestStart() method from “MyServlet extends VaadinServlet” is executed before the initialisation of the first UI ?
This point was better with Vaadin 6 because all was in the same class !
I think you’re doing things the wrong way around. There can be multiple StartingClass instances per session - one for each open browser tab, and in addition there may be closed ones that are not yet cleaned up. (For example, refreshing the browser window will create a new UI instance by default.) You should instead access the servlet in StartingClass - for instance calling VaadinServlet.getCurrent().
Ok. In fact, i would like to integrate a WIndows SSO (Single Sign On) like Waffle, inside my Vaadin7 application.
I created another thead => “Vaadin7: How to integrate a “Single Sign On” like Waffle ?”
