Re: [ecf-dev] Using a container multiple times

Hi Robert,

I have decided to go with the ECF method at the moment, because it
gives me more control over discovery etc. and I can also like to
retain responsibility for creating the container

So on the client side, I will wait for the container connection, then
pick up the shared object, then pick up the remote service:

container = manager.getContainerFactory().createContainer("ecf.generic.client");
container.addListener(new IContainerListener() {

public void handleEvent(IContainerEvent event) {
	if (event instanceof IContainerConnectedEvent)
	try {
ID id = IDFactory.getDefault().createID(container.getConnectNamespace(),
//pick up the shared object														ISharedObjectContainer soc =
(ISharedObjectContainer) ((IAdaptable)
													ISharedObjectManager manager = soc.getSharedObjectManager();
EventAdmin admin = new DistributedEventAdmin(context);
ID id1 = IDFactory.getDefault().createStringID("");
Properties props = new Properties();
props.put(EventConstants.EVENT_TOPIC, "uk_co_xlegal_xbundle3_remote");
manager.addSharedObject(id1, (ISharedObject) admin, props);
((DistributedEventAdmin) admin).start();
//now pick up the remote service									
IRemoteServiceContainerAdapter rsc = (IRemoteServiceContainerAdapter)
((IAdaptable) container).getAdapter(IRemoteServiceContainerAdapter.class);
														IRemoteServiceReference[] refs =
event).getTargetID(), StateProvider.class.getName(), null);
StateProvider provider = (StateProvider) rsc.getRemoteService(refs[0]);
Map<String, Object>  state = provider.provideState();
} catch (Exception e) {
														Log.log(Log.ERROR, e.getMessage());
container.connect(id, null);

I'm finding that refs is null. Looking inside rsc, I see that the
remoteRegistry array is empty.
Have I missed a step in initialising the
IRemoteServiceContainerAdapter on the client side?

I don't think so...I think probably the issue is that you should use this lookup method (note the ID[] first param, rather than ID):

IRemoteServiceReference[] refs =
rsc.getRemoteServiceReferences(new ID[] { ((IContainerConnectedEvent)
event).getTargetID() }, StateProvider.class.getName(), null);

I have other commitments right now so can't explain at the moment, but I suspect that this will deal with this situation.
