I will repeat myself : I would look into Athmosphere.
This is a wrapper around websockets so you don't have to do the bear bones
stuff yourself. And they talk about GWT on their Github page
: https://github.com/Atmosphere/atmosphere-extensions/wiki/Atmosphere-GWT
I used SignalR which is also a
There are several pollyfills for eventsource though. Just like there are
for older browsers and websockets.

Others have suggested websockets, but there are several other options as
well. There is google cloud messaging and many other libraries to solve
this problem as well as ServerSent Events.

If none of those are options, try to avoid
Make a timer that fires every X seconds.
Button refresh = new Button();
Time temporizador = new Timer() {
@Override
public void run() {
dispara();
}
};
// 2 seconds
temporizador.scheduleRepeating(2000);
If you only need to support modern browsers then I really would go the
WebSockets way. Its really simple to implement with JSInterop. I did so in
combination with GWT Jackson and RequestBuilder. On the server side I used
Jersey. Unfortunately I cannot publish this code since it is closed source.
I do this using signalR (for which I built a GWT wrapper (not opensource).
But maybe you should look into websockets or atmosphere (which uses
websockets).

Simplest solution a timer that polls the DB every 10sec let's say.
If you want a truly asynchronous server side notification you should look
at websockets or long polling...
