I have a remote server application running locally and on a remote host (10.1.1.33). The client is connecting to the local instance even though I configured it to connect remote instance. Is there something else I need to configure?
private static final int DEFAULT_PORT = 3787;
private static String HOST= "10.1.1.33";
private BundleContext bundleContext;
private RemoteConfigurationUtil proxy;
private List<IProxyListener> listeners= new ArrayList<>();
private ServiceTracker<RemoteConfigurationUtil, RemoteConfigurationUtil> st;
public RemoteServiceTracker() {
this.bundleContext=Activator.getContext();
IGenericServerContainerGroup group;
try {
ServiceReference<IGenericServerContainerGroupFactory> sr = bundleContext.getServiceReference(IGenericServerContainerGroupFactory.class);
IGenericServerContainerGroupFactory proxy = bundleContext.getService(sr);
group = proxy.createContainerGroup(HOST, DEFAULT_PORT, null);
group.createContainer("/server");

The snippet I posted was for the client. Here is the server code.
Dictionary<String, String> dict = new Hashtable<String, String>();
// add OSGi service property indicated export of all interfaces exposed
// by service (wildcard)
dict.put(IDistributionConstants.SERVICE_EXPORTED_INTERFACES, IDistributionConstants.SERVICE_EXPORTED_INTERFACES_WILDCARD);
// add OSGi service property specifying config
dict.put(IDistributionConstants.SERVICE_EXPORTED_CONFIGS, CONTAINER_TYPE);
// add ECF service property specifying container factory args
dict.put(IDistributionConstants.SERVICE_EXPORTED_CONTAINER_FACTORY_ARGUMENTS, "ecftcp://localhost:3787/server");
try {
bundleContext.registerService(new String[] {
ConfigurationUtil.class.getName(), EMailUtil.class.getName(), ServiceUtil.class.getName(),
RemoteConfigurationUtil.class.getName()} , new RemoteConfigurationUtilImpl(props), dict);
log.info("RemoteConfigurationUtilImpl RemoteService registered");
}catch(Exception e){
e.printStackTrace();
}
I am using jmdns, but I really don't need discovery because I only need to connect to a static IP. This was the closest example that I could find for a point to point connection.
10.1.1.33 is the ip of the server, it is on the same lan as the client.
Thanks,
Greg

Hi Greg,
with this configuration you will end up with JmDNS announcing your
service as "ecftcp://localhost:3787/server" and consumers will obviously
fail to connect to the remote service provider but connect to localhost
instead. Try without SERVICE_EXPORTED_CONTAINER_FACTORY_ARGUMENTS or at
least set the hostname to the external name of the machine providing the
service.

Markus,
Using Wire Shark I looked at the communications and determined that the problem is probably caused by the VPN configuration not passing the mDNS packets. After a little research I decided that zookeeper would be a better fit for the application, and have been able to make it work.
Thanks for your support!
