GWT auto refresh

问题

I am working in GWT project. As per the requirement, i have to provide auto-refresh to one of my screen. My senior told me to use <meta http-equiv="refresh" content="300"> in that screen page.

But as GWT code is written in java only, so i wonder how can I use it in java file.

Can somebody help?

Depending on how you are managing history and if you are not using places. You can use the location reload event inside a timer.

If you are using places, you can use your place controller to re navigate to the same place every 30 seconds

Timer t = new Timer() {
    public void run() {
        Window.Location.reload();
    }
};
t.scheduleRepeating(30000);
