Hi everybody! I meat the following problem. When my GWT app is
started it is very necessary to make an asynchronous call - to gether
some data. If i make this call directly from OnModuleLoad() method -
then i getting the result, but when I putting the call of my method in
a thread:
OnModuleLoad
Java script is sigle threaded, you can not use threads in the client side of
gwt project. Just use AcyncCallback.

Thanx, the answer is clear, but if JavaScript is a single-threaded,
then how this code can works?
private void makeATL(final String router) {
Runnable onLoadCallback = new Runnable() {
public void run() {
//some code
I never used runnables in my client gwt code, look what js is generated from
this code.
See this to comfirm my statement:

I suppose all runnable are invoked in one thread without new thread
creation.

Why not. Just run it "later" in a same thread.

SergeZ,
In your first example, simply instantiating a Runnable does nothing--you
need to call run() on it to make it run. But this doesn't make it run on a
different thread. To run it on a different thread, you'd have to instantiate
Thread using the Runnable instance as a constructor argument.

Thanks to your all for answers on my question! I'll try to call the
run() method ( how can I\ forgot to call it)) ). But I thinking that
it will not helps me...
Actually, I have the one concrete task - create some similarity to
monitoring system. My software must receive data from DataBase and
re
If you use a timer, your data will be delayed by up to the period of the
timer (e.g. if your timer fires every 5 seconds then there will be a delay
of up to 5 seconds to display your data).
Rather than an infinite while or for loop, you can "loop" by having the RPC
call's AsyncCallback onSuccess a
SergerZ, infinity loop never seems to be a good idea.
You won't ever get realtime behaviour as you can't get out from
client-server paradigm. So only emulate. This timer solution is good.
Btw, maybe you want to look at http://code.google.com/p/rocket-gwt/ server
push technology.

Can you give a simple example of how to make this "looped"
asynccallback call ?

Thanks for the reference. This feature is very interesting!

You might want to have something like comet. Take a look at

I just meant something like this.
void *pollForEvents() *{
server.getEvents(new AsyncCallback() {
public void onSuccess(Event[] result) {
handleEvents(result);
*pollForEvents();*
}
public void onFailure(Throwable caught) {
// do something with the error...
if
final Timer t=new Timer() {
int i=0;
@Override
public void run() {
greetingService.getDataHit(
new AsyncCallback() {
Thanks a lot for you all I currently stopped at timer's solution -
just for quickly gett the working app, and further I planned to use
GWTeventservice library - it's a very useful feature.
