How can I open the default system browser from a java fx application?

I'm trying to open a web url in the default system browser from javafx. I didn't find any official documentation regard this. Any clue?

EDIT: I've found a tutorial but it doesn't work. I'm using MacOsX and I tried launching

java.awt.Desktop.getDesktop().browse(new URI(url));

but I get an HeadlessExcelption

Use hostServices.showDocument(location).

Try placing the following code in your application's start method:

getHostServices().showDocument("http://www.yahoo.com");

Complementing jewelsea's answer, if you don't know how to call getHostServices() then try this at your main class:

HostServicesDelegate hostServices = HostServicesFactory.getInstance(this);
hostServices.showDocument(WEBSITE);

http://docs.oracle.com/javafx/2/api/javafx/application/HostServices.html#showDocument(java.lang.String)

Another option is to use ProcessBuilder:

public static void openWebpage(String url) {
    try {
        new ProcessBuilder("x-www-browser", url).start();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

You can use this option if Desktop.getDesktop().browse(uri) for some reason hangs without any error.
