Exception in thread "main" java.lang.NullPointerException at suncertify.gui.Client.setTable(Client.java:69)
All the necessary methods throw RemoteExceptions.
More information may be needed from me to clarify things, but what I'm really after is an understanding of what the general issue is here, as far as "illegal remote method" and "illegal remote interface" are concerned. They are coded as per Monkhouse's design.
The issue with the Lock method is baffling above all, since I haven't yet invoked it at all, anywhere, and it is only one of the methods in the DB interface. I can't understand why it is being singled out.
I don't want to paste large swathes of code, so if any specific information is further needed, please let me know and I will try and explain in more detail what is required.
Any general conceptual help would be most appreciated.
