Re: Google Gadget: works in hosted mode, but not in web mode (iGoogle)
I have still difficulties with RPC call in a gadget. In hosted mode it
works again, but not in iGoogle.
Here is my Code:
package com.google.gwt.sample.cnsnews_rpc_gadget.client;

@ModulePrefs(title = CADENAS News, author = mr)
public class CADENASNews_RPC_Gadget extends GadgetNewsPreferences
implements NeedsIntrinsics, AsyncCallbackString
{
IntrinsicFeature intrinsicMethods;
private final static GadgetServiceAsync gadgetService =
(GadgetServiceAsync) GWT.create(GadgetService.class);
static {
disableStats();
}
private static native void disableStats() /*-{
$wnd.$stats = null;
}-*/;
public void initializeFeature(IntrinsicFeature feature) {
this.intrinsicMethods=feature;
}
public void init(NewsPreferences preferences) {
ServiceDefTarget serviceDef = (ServiceDefTarget) gadgetService;
String rpcUrl = serviceDef.getServiceEntryPoint();
rpcUrl = intrinsicMethods.getCachedUrl(rpcUrl);
String protocol = rpcUrl.substring(0, rpcUrl.indexOf(':'));
String file = rpcUrl.substring(rpcUrl.indexOf('/',
rpcUrl.indexOf
(':')+3));
serviceDef.setServiceEntryPoint(protocol+://+ getDomain() +
file);
RequestBuilder requestBuilder = gadgetService.getXML
(CADENASNews_RPC_Gadget.this);
String url = requestBuilder.getUrl();
makeGetRequest(url, requestBuilder.getRequestData(),
requestBuilder.getCallback());
}
private static native String getDomain() /*-{
return $wnd.document.domain;
}-*/;
public void onFailure(Throwable caught) {
Label lbl2 = new HTML(caught.getLocalizedMessage());
RootPanel.get().add(lbl2);
}
public void onSuccess(String result) {
Label lbl = new HTML(result);
RootPanel.get().add(lbl);
}

};
}-*/;
static void onSuccessInternal(final GadgetResponse response,
RequestCallback callback) {
try {
String responseText = response.getText();
callback.onResponseReceived(null, new
FakeResponse(response));
} catch (Exception e) {
callback.onError(null, e);
}
}
}
Does anyone know what's wrong here?

It may help to checkout the gwt-gadgets project from code and build a fresh

This may be a conflict between different versions of xerces, because this part of the code is creating a new XML document. You should be using the -noredist.jar file, and expecting to resolve xerces in your GWT build. Are you explicitly including xerces in your build classpath?
