[ecf-dev] Async-Methods

[Eugen Reiswich <ereiswich@xxxxxxxxxxxxxx>]

Hi folks, 

I just found out that ECF also supports async-methods  and tried to set up a small example using the XMPP-provider. Unfortunately I get an exception trying to call async-methods: java.lang.NoSuchMethodException.

Just to make sure I got everything right:

1. I have a service called IExampleService:

public interface IExampleService {

public String getName();

}

2. I've created a second Interface: IExampleServiceAsync in the same package:

public interface IExampleServiceAsync extends IAsyncRemoteServiceProxy {

public void getNameAsync(String param, IAsyncCallback<String> callback);

} 

3. My ServiceImpl implements both interfaces (I've also tried it without implementing IExampleServiceAsync, but same exception):

public class ExampleServiceImpl implements IExampleService,

IExampleServiceAsync {

@Override

public String getName() {

return "ExampleService";

}

@Override

public void getNameAsync(String param, IAsyncCallback<String> callback) {

System.out.println("ExampleServiceImpl.getNameAsync()");

callback.onSuccess(getName() + "yeahhh!!!");

}

}

4. I've registered the service twice using only one interface:

getRemoteServiceContainerAdapter().registerRemoteService(new String[] { IExampleService.class.getName()}, service,

null);

5. I've started service host and consumer with the ECF-bundles attached in the screenshot.

6. Get the a remote service proxy (using a helper method):

IExampleServiceAsync remoteService = (IExampleServiceAsync) sessionService

.getRemoteServiceForClient(IExampleService.class.getName(),

clientID, null);

7. When I try to call the async method "getNameAsync" on the proxy I get an exception saying:  java.lang.NoSuchMethodException: No such method: getName([class java.lang.String])

remoteService.getNameAsync("test", new IAsyncCallback<String>() {

@Override

public void onSuccess(String result) {

System.out.println("   ++++ onSuccess: Remote service says: "+ result);

}

@Override

public void onFailure(Throwable exception) {

System.out.println("   ++++ onFailure: Remote service says: "+ exception);

}

}); 

Regards,

Eugen
