org.omg.CORBA.TRANSIENT: initial and forwarded IOR inaccessible, after migration to version 8.



Running Application Client, remotely connecting to WebSphere Application Server (WAS) version (after migration from version 7) on the server side, getting error: 'javax.naming.NamingException: Error getting WsnNameService properties [Root exception is org.omg.CORBA.TRANSIENT: initial and forwarded IOR inaccessible vmcid: IBM minor code: E07 completed: No] at at at at at at at at at javax.naming.InitialContext.lookup(


Server side has CSIv2 Transport Layer -> Transport set to SSL-Required, which is the default in WAS version 8, but client side was not set up for SSL.

Resolving The Problem

Go to the WAS Administrative Console and change the WAS Global Security settings, specify the CSIv2 inbound and outbound transports to "SSL-Supported", restart the server

Security -> Global security, then go to CSIv2 inbound communications (and outbound communications as well) -> CSIv2 Transport Layer -> Transport, change SSL-Required (the default in V8) to SSL-Supported

Common Secure Interoperability Version 2 transport inbound settings
