com.google.gwt.jsonp.client.JsonpRequestBuilder

google.com/apis/gdata/json.html#Request">JSON Google Calendar GData API:

 String url = "http://www.google.com/calendar/feeds/developer-calendar@google.com/public/full" + "?alt=json-in-script"; JsonpRequestBuilder jsonp = new JsonpRequestBuilder(); jsonp.requestObject(url, new AsyncCallback<Feed>() { public void onFailure(Throwable throwable) { Log.severe("Error: " + throwable); } public void onSuccess(Feed feed) { JsArray<Entry> entries = feed.getEntries(); for (int i = 0; i < entries.length(); i++) { Entry entry = entries.get(i); Log.info(entry.getTitle() + " (" + entry.getWhere() + "): " + entry.getStartTime() + " -> " + entry.getEndTime()); } } });

This example uses these overlay types:

 class Entry extends JavaScriptObject { protected Entry() {} public final native String getTitle() /*-{ return this.title.$t; }-*/; public final native String getWhere() /*-{ return this.gd$where[0].valueString; }-*/; public final native String getStartTime() /*-{ return this.gd$when ? this.gd$when[0].startTime : null; }-*/; public final native String getEndTime() /*-{ return this.gd$when ? this.gd$when[0].endTime : null; }-*/; } class Feed extends JavaScriptObject { protected Feed() {} public final native JsArray<Entry> getEntries() /*-{ return this.feed.entry; }-*/; }
