Re: [ecf-dev] Async-Methods

[Eugen Reiswich <ereiswich@xxxxxxxxxxxxxx>]

Thank you all for your help! I guess I'll try the RemoteProgressService solution. 

Regards,

Eugen

Hi Eugen,

Yes, that is correct. But you can show a never ending progress in a job.

Alternatively you can make a remote ProgressService that gets a ping every 1000 kunden-objects. 

Regards,

Wim

Hi Markus, 

taking the example below: say I have 10000 Kunden-objects which I need to read from e.g. a database. This might take a while therefore I would like to use an async-method to avoid time out exceptions. But in addition to that I would like to send say each 100 found Kunden-objects a progress update to the client so he knows something is happening on the server side. The example below will only inform when the job is done without any steps in between, right? 

final IFuture kunden = serviceAsync.listKundenAsync();
					try {
						// do something else here before kunden gets used
						// doSomeHeavyComputation();


						if(kunden.isDone()) {
							setInput((Kunde[])kunden.get());
						}
						// finally wait for 1000ms to set the input and fail otherwise 
						setInput((Kunde[]) kunden.get(1000));
					} catch (OperationCanceledException e) {
						//TODO handle e somehow, but how?
						e.printStackTrace();
					} catch (InterruptedException e) {
						//TODO handle e somehow, but how?
						e.printStackTrace();
					} catch (TimeoutException e) {
						//TODO handle e somehow, but how?
						e.printStackTrace();
					}

Regards,

Eugen

Hi Eugen,

check my slides (and code examples [0]) from the OSGi summer school. It

shows how to use an IFuture.

One more source for an example is the demo code that we used for ESE2010
