RAD publishing problem and corba errors

I was deploying an application in rad 7 and was 6.1 server. I received below mentioned error. It took lot of time to figure some changed virtualHostName entry
in ibm-web-bnd.xmi to some random name from default_host. This should always be default_host.

Error:
Publish failed with errors, warnings or both. Please see server logs for more details.
