[omniORB] [omniORBpy] omniORB.CORBA.TRANSIENT: CORBA.TRANSIENT(omniORB.TRANSIENT_ConnectFailed, CORBA.COMPLETED_NO)

[loretta]

Dear omniORB Users,


when I run code similar to that in the tutorial (chapter 2.6.3 "Server code")
shown below, I get this error:

Traceback (most recent call last):
File "sensors_server.py", line 38, in <module>
root_context = obj._narrow( CosNaming.NamingContext)
File "/usr/lib/python2.5/site-packages/omniORB/CORBA.py", line 787, in
_narrow
return _omnipy.narrow(self, repoId, 1)
omniORB.CORBA.TRANSIENT: CORBA.TRANSIENT(omniORB.TRANSIENT_ConnectFailed,
CORBA.COMPLETED_NO)

The code is


from omniORB import CORBA, PortableServer
import CosNaming, Sensors, Sensors__POA


class Sensor4DistancesImplementation(Sensors__POA.Sensor4Distances):

def current_value( self):
return time.time()


orb = CORBA.ORB_init( ["-ORBInitRef", "NameService=corbaname::localhost"],
CORBA.ORB_ID)
poa = orb.resolve_initial_references( "RootPOA")

sensor_imp = Sensor4DistancesImplementation()
sensor_ref = sensor_imp._this()

obj = orb.resolve_initial_references( "NameService")
root_context = obj._narrow( CosNaming.NamingContext)
if root_context is None:
print "Failed to narrow the root naming context!"
sys.exit( 1)


The exception occurs in #_narrow:

def _narrow(self, dest):
repoId = dest._NP_RepositoryId
try:
dest_objref = omniORB.objrefMapping[repoId]
if isinstance(self, dest_objref):
return self
except KeyError:
pass
return _omnipy.narrow(self, repoId, 1) # <= Exception is raised here


There seems a part of a program not running, which my program wants to connect
to. Any pointers?

As I am new to this CORBA stuff, please let me know what additional info I
could provide to nail the problem down.

I am on Linux (Ubuntu 8.04), Python is of version 2.5.2:

Kind regards

That code is trying to access the naming service, but it's not there.
You need to run omniNames.

Cheers,
