Vaadin 6 / 7 / 8

Hi

Anybody help me to find a solution to send notification to particular machines by getting their IP addresses in vaadin

You can find out the IP of a particular vaadin client by using Application.getContext(), casting the result to WebApplicationContext, and then using getBrowser().getAdress().

The context also has a getApplications() method that will return all active Application instances. From that application you can the use the normal getMainWindow() etc, but remember to synchronize all accesses to Application objects on the Application object itself!
