Dear gurus,
I'm learning Java and GWT and I'm facing a problem with setting timeout for
PRC calls. I want to extend the RPC timeout before the client reports a
failure. The code I'm using is attached below.
I'm running a client in firefox and experience the following problem:
I want to achieve a timeout of 20-30 seconds. However I can set the timeout
(RPC_TIMEOUT_MS) only up to 3200mS. In case the server does not respond I
receive the exception "*com.google.gwt.http.client.RequestTimeoutException:
A request timeout has expired after 3200 ms*" accurately after defined time.
However in case set timeout exceeds the 3300ms of above the exception is
different "*com.google.gwt.user.client.rpc.StatusCodeException: 0*" and is
thrown always after 3-4 seconds.
What causes this exception and how can I extend the waiting time?
Thank you,
Best regards
Dmitri
The code:
public class MyClass implements EntryPoint {
private static final int RPC_TIMEOUT_MS = 3300;
private static class TimeoutRequestBuilder extends RpcRequestBuilder {
@Override
protected RequestBuilder doCreate(String serviceEntryPoint) {
RequestBuilder builder = super.doCreate(serviceEntryPoint);
builder.setTimeoutMillis(RPC_TIMEOUT_MS);
return builder;
}
}
private static final RpcRequestBuilder requestBuilder = new
TimeoutRequestBuilder();
private final HubServiceAsync myService = GWT.create(HubService.class);
@Override
public void onModuleLoad() {
((ServiceDefTarget) hmyService).setRpcRequestBuilder(requestBuilder);
final MainView mainView = new MainView(hubService);
RootPanel rootPanel = RootPanel.get();
rootPanel.add(mainView);
Window.addResizeHandler(new ResizeHandler() {
@Override
public void onResize(ResizeEvent event) {
mainView.resize();
}
});
}
}
