Examples of com.google.gwt.http.client.RequestBuilder.sendRequest()

com.google.gwt.http.client.RequestBuilder.sendRequest()
Sends an HTTP request based on the current builder configuration with the specified data and callback. If no request headers have been set, the header "Content-Type" will be used with a value of "text/plain; charset=utf-8". This method does not cache requestData or callback. @param requestData the data to send as part of the request @param callback the response handler to be notified when the request failsor completes @return a {@link Request} object that can be used to track the request @throws NullPointerException if callback null

    public void doGet(String url, RequestCallback callback) {
      RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, url);
      responseState = State.COMPLETED;


      try {
         Request response = builder.sendRequest(null, callback);
      } catch (RequestException e) {
         responseState = State.ERROR;
         errorMessage = e.getMessage();
