I want to call a php file on my server to provide a weather service.
When I'm running in hosted mode, response.getStatusCode() gives 0
(zero). Is there a way to make this work in hosted mode?
public class IMFPanelWeather extends Composite {
private VerticalPanel table = new VerticalPanel();
private HTML mIcon = new HTML();
private HTML mConditions = new HTML();
private HTML mTemperature = new HTML();
private HTML mHumidity = new HTML();
private HTML mClouds = new HTML();
public IMFPanelWeather() {
callServerPage();
table.add(mIcon);
table.add(mConditions);
table.add(mTemperature);
table.add(mHumidity);
table.add(mClouds);
initWidget(table);
}
private void callServerPage() {
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,
URL.encode("http://www.myserver.com/weather.php5";));
try {
builder.sendRequest(null , new RequestCallback() {
public void onError(Request request, Throwable
exception) {
requestFailed((RequestException)exception);
}
public void onResponseReceived(Request request,
Response response)
{
if (200 == response.getStatusCode()) {
try {
// The response was
successful
JSONValue jsonValue =
JSONParser.parse(response.getText());
JSONArray jsonArray =
jsonValue.isArray();
if (jsonArray != null) {
updateTable(jsonArray);
} else {
throw new
JSONException();
}
} catch (Exception e) {
// There has been a
problem on the server.
mConditions.setHTML("No
data");
}
}
}
});
}catch(RequestException e) {
requestFailed(e);
}
}
private void requestFailed(RequestException pException) {
mConditions.setHTML("Request failed");
System.out.println("Weather request failed.");
}
}
