a simple POST with formData

Hi, I have this code:

public native void callServer() /*-{
var fd = new FormData();
fd.append("fileField", "hola");
var xhr = new XMLHttpRequest();
xhr.open("POST", "file_handler.php");
xhr.send(fd);
}-*/;

But the debug say:
....:FormData is not defined

I can't do this with GWT ??!! I really don't understand why not found
a javascript funcion ...

thanks for all.
