How I can get an url of the window?

Question

I use java and vaadin

I do window.getURL() and it returns me, for example - 99.22.22.22:8080/2/ However, it's supposed to return app.server.com/2/

of course, app.server.com is the same as 99.22.22.22:8080

But how I can replace it by app.server.com??

Here is the answer How to get the Vaadin 7 application server IP and port? i guess.

Please try this:

System.out.println(UI.getCurrent().getPage().getLocation().getHost());
System.out.println(UI.getCurrent().getPage().getLocation().getPath());
System.out.println(UI.getCurrent().getPage().getLocation().getPort());

Or get hostname by ip:

InetAddress addr = InetAddress.getByName("99.22.22.22");
String host = addr.getHostName();
System.out.println(host);
