Re: [ecf-dev] ECF-RFC119 with R-OSGi and SLP discovery: ClassCastException 
Hi Juergen,
Some questions about the below (BTW, would you please open as a bug and even if it turns out not to be a bug...or something in slp, we'll deal with that). Thanks! 

Questions:

What distribution provider are you using (i.e. r-osgi, or some other?)
JmDNS does not show this error using the same provider, right?
Just for everyone's reference, the Long is added to the discovery metadata in this method:
org.eclipse.ecf.internal.osgi.services.distribution.EventHookImpl.getServicePublicationProperties(IRemoteServiceContainer, ServiceReference, String[], IRemoteServiceRegistration) 

on line 182
Markus...is there some possibility that jSLP is changing a Long into an Integer somewhere along the discovery way? 

In any case, we'll check this out.

Scott

Hi,
I'm currently experimenting with your RFC119 implementation which we want to use in SMILA soon. I have it working now when using the JMDNS discovery but not with the jSLP discovery. I'm quite 
sure the reason is this stacktrace:

java.lang.ClassCastException: java.lang.Integer
	at org.eclipse.ecf.osgi.services.discovery.RemoteServiceEndpointDescription.getRemoteServiceId(RemoteServiceEndpointDescription.java:181)
	at org.eclipse.ecf.internal.osgi.services.distribution.DiscoveredServiceTrackerImpl.containsDiscoveredServiceID(DiscoveredServiceTrackerImpl.java:654)

	at org.eclipse.ecf.internal.provider.jslp.JSLPDiscoveryJob.run(JSLPDiscoveryJob.java:57)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

When I changed the cast in this method to (Number), the discovery succeeds. I've not found the place yet,
where the Integer is added instead of a Long. I'm using Declarative Services both to start the service that
is to be distributed, and to start a client service that is bound to the remote service using DS references.
Is this a bug or am I doing something wrong?

Regards,
Jürgen
