Re: [ecf-dev] Problem with Remote Services

[Scott Lewis <slewis@xxxxxxxxxxxxxxxxx>]

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.
