Re: [ecf-dev] Problem with Remote Services
I found a small bug in filter declaration:
context.createFilter("(&("+org.osgi.framework.Constants.OBJECTCLASS+"=" + IHello.class.getName() +")(" + REMOTE + "=*))");
There should be REMOTE_INTEFACE instead of REMOTE.
Can you explain how to run consumer and host applications on two machines?
I suppose that I should change container creating in consumer activator: 
ContainerFactory.getDefault().createContainer("ecf.r_osgi.peer", new Object[] { IDFactory.getDefault().createStringID("r-osgi://localhost:9278") });
where localhost should be an address of the machine where host is running but it doesn't work.

Hello Wojciech,

Thanks for the report.

The 'error' (i.e. No IDiscoveryAdvertiser available to handle this publication) is/was changed to warning as per this bug:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=278149.  All it indicates is that there is no container available within the host process to receive the proxy create notification.  It's not an actual error.

The conflict you are seeing when running both consumer and host on the same machine is most likely a port-level conflict with r-OSGi.  r-OSGi tries to use port 9278 by default and if an instance is already running on the host (e.g. within Eclipse), then running the example consumer and client will conflict, and things won't work.

I need to add documentation to this effect on the wiki...and to provide workarounds for single-host testing.

There is also this bug report https://bugs.eclipse.org/bugs/show_bug.cgi?id=267521 germane to this issue.

I didn't recognize that client doesn't work. When I run customer and host on the same machine it works only if I change:
helloServiceTracker = new ServiceTracker(context,createRemoteFilter(),this) to helloServiceTracker = new ServiceTracker(context, IHello.class.getName(), this). If I try to connect with remote service consumer does nothing. When I run host I see information below:

The same error I have during each of tests in org.eclipse.ecf.tests.osgi.services.distribution r-osgi tests.

       Hi Wojciech,

       Would you consider contributing back your launch configs for
       the host and consumer?  Since I've been working with the
       bundles in my workspace, the existing launch configs don't
       work (as you discovered)...and it would be much better to have
       'clean' launch configs.

       If you wouldn't mind doing this, would you open a bug report
       and attach the launch configs to that bug report?

       Thanks much in advance,

       Scott

              Wojciech,

              This indicates that the container type that you are
           creating (in
              this case r-osgi) is not present in your runtime
           configuration.
               To use r-osgi provider you need:

              org.eclipse.ecf.provider.r-osgi
              ch.ethz.iks.r_osgi.remote
              org.objectweb.asm

              I've opened this bug to improve the exception message
           so that this
              is clearer:
            https://bugs.eclipse.org/bugs/show_bug.cgi?id=278222

              Thanks,

                  I have the same situation with
                            org.eclipse.ecf.examples.remoteservices.hello.consumer/client
                  example. I didn’t modify any code. Probably it’s
           very easy to
                  resolve but it’s my first touch with ECF.
