I just bought the book and I was trying the first example in the first chapter. I followed the procedure in the book step by step. I could compile all the files but when I run client program, I got a long list of exception. I am a newer in the field, so I have no idea what's going on. The exception lists is as the following:
java.rmi.RemoteException: CORBA BAD_OPERATION 0 No; nested exception is:
org.omg.CORBA.BAD_OPERATION: vmcid: 0x0 minor code: 0 completed: No
