This message indicates that although the service is discovered, there
are no client remote service containers created to use it.
On the consumer/client side...which product are you starting from? It
looks like you are using the ECF generic provider on the service host
(i.e. ecf.generic.server is what is used on the host)...but are you
starting the client with -containerType ecf.generic.client (the default
is r-osgi...and since you are using the ecf.generic.server on the
service host the consumer does not have a compatible container type when
discovered, and that's why it says: "No local RemoteServiceContainers
found for endpoint...")
At least that's the way it looks. Not that the product configurations
(in products directory in hello.consumer project) have products that can
be used to determine which provider to use when launched. These
products just specify a command line parameter...e.g. -containerType
ecf.generic.client that specifies the type of container to create for/on
the client.
The main/important thing is that the container type is
appropriate/compatible on both ends (i.e. ecf.generic.server and
ecf.generic.client...or ecf.r-osgi.peer on both).
BTW, you can set a breakpoint on line 57 of
org.eclipse.ecf.internal.examples.remoteservices.hello.consu mer.HelloConsumerApplication
and you can see what the container type is by examining the value of the
containerType member variable.
Hope this helps. Please let all know if this does not fix what you are
experiencing.
Scott
