beans
First, I'm afraid we're going to need much more of the server
output than you provided. It would be simplest to dump it all, but
certainly the entire stack trace for any exceptions would be helpful.
Also, as for MalformedURLExceptions, we see things like that
when you deploy on Windows into a directory with spaces in the name. Have
you done that here? If so, please try again in a directory without
spaces. We're working on the problem now.
The exception you do quote looks like a ClassCastException (that's
usually the kind that prints a class name to the console). Did you
perhaps try to look up a CustomerBean with the JNDI name of the
ReservationBean instead? Could you provide the exact source code that
corresponds to the exceptions you're seeing?
Thanks,
Aaron
