Open new window with ABSOLUTE url path

I have a table with addresses. I have a button you can click which I want to open a google search for the address in a separate window. I have tried

getUI().getPage().open(url, "_blank"

and

BrowserWindowOpener opener = new BrowserWindowOpener(url);
opener.extend(googleBtn

but both are appending my url to the current path. I want to simply run a search in google in a separate window. I’m sure this is much simpler than I’m making it. It sure should be, at least. Thanks.

This doesn’t work?

[code]
@Override
protected void init(VaadinRequest request) {
    final VerticalLayout layout = new VerticalLayout();
    BrowserWindowOpener opener = new BrowserWindowOpener("http://www.google.com/");
    Button button = new Button("google.com");
    opener.extend(button);
    layout.addComponent(button);
    setContent(layout);
}

[/code]
