Here is a link to help you to do what you want:
http://code.google.com/webtoolkit/doc/latest/tutorial/Xsite.html
If not, you can play a work around with native script and json. You
can comunicate by native javascript to an external script of your page
(out of gwt), send and ajax request and feed a json variable wich
could be accessed by gwt (again, via native script).
Examples:
public native void sendParameterToAnExternalService(String param1,
String param2)/*-{
$wnd.nativeAjaxCallImplementationInGeneratedBlahBlahHtml_Service(param1,
param2);
}-*/;
public native String getContextoSessionString()/*-{
return $wnd.jsonvariable;
}-*/;
Let me know if it helps you.
I'm glad to know that you are from Argentina. You don't know how
difficult is to me to explain in english :).
Saludos! (regards)
