below is the code where i execute the rpc request. i create getdata()
and getdata1() to get execute different query. i am using two Async
object to make call. i am not sure is it correct as i got error when
i use one. any help/advice is welcome and appreciated. :D
private void getData() {
AsyncCallback<Object> callback = new AsyncCallback<Object>() {
// fail
public void onFailure(Throwable ex) {
RootPanel.get().add(new HTML(ex.toString()));
}
// success
public void onSuccess(Object result) {
// Cast the result into the object that was sent
// This casts the random object into DataContainer
// Since the object is an array we use []
DataContainer[] displayData = (DataContainer[]) result;
}
};
callProvider.getData(callback);
}
private void getData1() {
final int value1 = value;
AsyncCallback<Object> callback1 = new AsyncCallback<Object>(){
// fail
public void onFailure(Throwable ex) {
RootPanel.get().add(new HTML(ex.toString()));
}
// success
public void onSuccess(Object result) {
// Cast the result into the object that was sent
// This casts the random object into DataContainer
// Since the object is an array we use []
displayData1 = (DataContainer[]) result;
}
};
// remote procedure call to the server to get the data
callProvider1.getData1(callback1);
}
