Troubleshooting
Problem
A remote client ORB connection, attempting to obtain an initial context with the provider URL, fails with a javax.naming.CommunicationException.
Symptom
Remote client exception:
javax.naming.CommunicationException: A communication failure occurred while attempting to obtain an initial context with the provider URL: "corbaloc:iiop:192.168.0.210:2810/NameServiceServerRoot". Make sure that any bootstrap address information in the URL is correct and that the target name server is running. A bootstrap address with no port specification defaults to port 2809. Possible causes other than an incorrect bootstrap address or unavailable name server include the network environment and workstation network configuration. [Root exception is org.omg.CORBA.COMM_FAILURE: purge_calls:1988 Reason: CONN_ABORT (1), State: ABORT (5) vmcid: IBM minor code: 306 completed: Maybe]
