Naming Service unavailable error

[J Waldinger]

Hi,
I am running an application in WAS 5 for the first time. The application compiles, installs, and starts up fine - no errors. Yet when I try and invoke an EJB, I get the following error:
NMSV0602E: Naming Service unavailable. A communications error occurred. A connection to the name server could not be made when attempting create an initial context.
I understand what this means, yet I am not sure how to check that it is set up correctly. Can anyone help?
Thank you,
Jamie

What port are you pointing to for your naming server. In past versions it was on 900, but in Websphere 5 its on the bootstrap port of the application server.
