Ice::NoEndpointException: no suitable endpoint available for proxy

Hi,

I am receiving this error when executing my client:
Reference.cpp:1585: Ice::NoEndpointException:
no suitable endpoint available for proxy `NavigationI -t @ CMUcobotAdapter'

The architecture is a registry, a server and a client using indirect proxy, with everything running on the same machine.

The registry is started with: 
icegridregistry --Ice.Config=/opt/cmu/registry.cfg

The content of /opt/cmu/registry.cfg is: 
IceGrid.Registry.Client.Endpoints=tcp -p 4061
IceGrid.Registry.Server.Endpoints=tcp
IceGrid.Registry.Internal.Endpoints=tcp
IceGrid.Registry.AdminPermissionsVerifier=IceGrid/NullPermissionsVerifier
IceGrid.Registry.Data=/opt/cmu/registry
IceGrid.Registry.DynamicRegistration=1

I also have a folder created on /opt/cmu/registry/

The server object adapter creation is: 
ic = Ice::initialize(argc, argv);
Ice::ObjectAdapterPtr adapter = ic->createObjectAdapterWithEndpoints("CMUcobotAdapter", "default -p 10110");
adapter->add(getInstance(), ic->stringToIdentity("NavigationI"));

The server is started with: 
./server --Ice.Config=/opt/cmu/server.cfg

The content of /opt/cmu/server.cfg is: 
CMUcobotAdapter.AdapterId=CMUcobotAdapter
CMUcobotAdapter.Endpoints=tcp
Ice.Default.Locator=IceGrid/Locator:tcp -p 4061

The proxy creation in the client is: 
Ice::ObjectPrx proxy = ic->stringToProxy("NavigationI@CMUcobotAdapter");
CMU::NavigationIPrx navigationPrx = CMU::NavigationIPrx::checkedCast(proxy);

The client is started with the comand: 
./client --Ice.Config=/opt/cmu/client.cfg

The content of /opt/cmu/client.cfg is: 
Ice.Default.Locator=IceGrid/Locator:tcp -p 4061

I cannot see the problem, with direct proxies everything was fine, but when I tried to move to an indirect proxie I get this error.

Do you see the problem?

Thanks in advance,
Carlos

    Hi Carlos,

    Which version of Ice are you using?

    Overwriting your endpoint configuration with createObjectAdapterWithEndpoints is unusual; why not create your object adapter with:
    Ice::ObjectAdapterPtr adapter = ic->createObjectAdapter("CMUcobotAdapter");

    Do you activate this object adapter?

    Best regards,
    Bernard

    Hi Bernard,

    thanks for your early reply.

    I've tried your suggestion for creating the object adapter and I get an additional error when I start the server: 
    ObjectAdapterI.cpp:774: Ice::InitializationException:
initialization exception:
object adapter `CMUcobotAdapter' requires configuration

    Do I need to add any extra conf. information inside the server.cfg?

    By the way I'am using Ice 3.3.1 and the object adapter is activated (previously I was using direct proxies without problems).

    Best,
    Carlos

    This exception means Ice can't find the CMUcobotAdapter.Endpoints property in the server configuration file--so it does not find AdapterId either, which explains the initial problem.

    The argc/argv parameters come directly from your main() function?

    Best regards,

    Bernard,

    that was the problem, I was ignoring argc and argv within my code.

    Now, it is working.

    Thanks as always!

    Hi Carlos,

    It's good to see you figured it out. You should also consider upgrading to Ice 3.4.2.

    Best regards,
    Bernard
