Hi, thanks for the tip, it works like a charm!
Here is some more detailed info for GWT beginners (like me).
Like Thomas wrote, in order to set timeout for RPC request, you need
to change your functions in xxxAsync interface. For instance instead
of:
void getServerInfo(String input, AsyncCallback<String> callback);
you should have:
RequestBuilder getServerInfo(String input, AsyncCallback<String>
callback);
And when you call the service, you must explicitly run send()
function. Example below:
RequestBuilder rb = serviceAsync.getServerInfo(input, new
AsyncCallback<String>() {
@Override
public void onSuccess(String result) {
}
@Override
public void onFailure(Throwable caught) {
}
});
rb.setTimeoutMillis(6000);
try {
rb.send();
} catch (RequestException e) {
}
Many thanks for both answers.
Cheers,
Andrzej
