I tried with Quartz schedular 1.8.6 with spring 3.1 for mail alerts showing popup in vaadin application. but am getting problem with popup ,it will not open in every quartz job trigger time.when ever the action is done in vaadin application then only it will open the window. So please rectify my problem.
Vaadin doesn’t have a push mechanism to automatically push any server-side changes made in the background (outside the normal request). The easiest solution is to add the
Refresher component to your user interface that will poll the server-side for changes periodically.
