After having bought the HeadFirst book and tried the first example, Even i ran into the same problem for about 3 days.
I havent had a chance to try what Kathy had suggested [System.out.printlns stmts] however i tried doing the rest of the steps[undeploy,cleanup,deploy etc] number of times[over past 3 days] but in vain.
Finally, it worked.
I removed the package headfirst statement in all my AdviceHome, Advice, AdviceBean
and removed the import headfirst stmt in AdviceClient. Kept all the classes looose in projects\advice\classes directory and client in projects\Advice directory
Rest of the steps have been followed by book.
It worked fine now without throwing the Corba exception.
But am curious to find out why it fails when i package them?
