I've run into a bit of a roadblock trying to get my transient name
service working, and I suspect it's because I'm missing some critical
step some place. In my test cases, I'm instantiating an ORB to host the
name service, intialized to listen on port 40001. This ORB has an
initial naming context activated on a POA instance using the following:
public void initialize(ORB orb) throws TransientServiceException {
try {
// get the root POA. We're going to re
POA rootPOA = (POA) orb.resolve_initial_references("RootPOA");
rootPOA.the_POAManager().activate();
// we need to create a POA to manage this named instance,
and then activate
// a context on it.
Policy[] policy = new Policy[3];
policy[0] =
rootPOA.create_lifespan_policy(LifespanPolicyValue.TRANSIENT);
policy[1] =
rootPOA.create_id_assignment_policy(IdAssignmentPolicyValue.SYSTEM_ID);
policy[2] =
rootPOA.create_servant_retention_policy(ServantRetentionPolicyValue.RETAIN);
POA nameServicePOA = rootPOA.create_POA("TNameService",
null, policy );
nameServicePOA.the_POAManager().activate();
// create our initial context, and register that with the
ORB as the name service
initialContext = new TransientNamingContext(orb,
nameServicePOA, null);
((org.apache.yoko.orb.CORBA.ORB)orb).register_initial_reference("NameService",
initialContext.getRootContext());
} catch (Exception e) {
throw new TransientServiceException("Unable to initialize
name service", e);
}
}
That all appears to be working correctly. Now to run a tests, I
initialize another ORB using the argument
args = new String[] { "-ORBInitRef",
"NameService=corbaloc::localhost:40001/TNameService"};
When I try to access the NameService using resolve_initial_references(),
I'm getting the following exception:
[server:err] org.omg.CORBA.OBJECT_NOT_EXIST: unable to dispatch -
servant or POA

Is there some additional registration required to make TNameService
accessible via a corbaloc: URL or is creating the TNameService POA
sufficient? I believe my server code is connecting with the name
service ORB ok, since I was originally getting some connection failures
until I sorted out getting the listener ports configured. Now it looks
like the two orbs are talking, but it's not able to resolve the context
object. I'm out of ideas on where to proceed from here.
