Or do you mean also loading the JS script?
BTW, you may want to start using GWT 2.8 (prefer the snapshot to the beta1,
if you can) and
JsInterop:

The equivalent of the above JSNI would be:
@JsMethod(namespace=JsPackage.GLOBAL)
static native boolean that_js_function(int param1, String param2, double
param3);
The equivalent of the JSNI that exposes your function would be:
@JsMethod(namespace=JsPackage.GLOBAL)
public static int js_funct_equiv(int myNum) {
return myNum;
}
(you'd need to pass the GWT compiler the --generateJsInteropExports flag to
export your method though.
