ClassCastException

[Peter Shipway]

Hello there,

The following statement is causing me a ClassCastException I have never seen this kind of error before and don�t quite know how to fix it.

try{
    System.out.println(members.getMember(0).toString());
    bank = (bankAccount) Naming.lookup("rmi://localhost/" + cmd);
    System.out.println(members.getMember(1).toString());   
}catch(Exception e){
    System.err.println("Problem: " + e);
}

I�m trying to create a distributed java RMI program that is capable of keeping a reference to itself and other instances of itself. (I.e. this one file is ran multiple times with different arguments in the command line)

Any help on this error would be greatly appreciated guys.

I just relized that I need to use the interface to refernce the RMI register instead, however I need to store a object of its own class in a list and I dont see how storing a list of the interfaces can help, is there a way that you can pull the "atucal" class from the register class?

Given code doesnot seems to be enough to comment on, atleast provide stacktrace

    public bankAccount(boolean b, String cmd) throws RemoteException{
        //Start timestamp at zero
        timestamp = 0;
        // Create new list of members
        members = new LinkedList();
        // Add this object to the list of members
        members.add(this);
        // Create new list of transactions
        transactions = new LinkedList();
        // Create new SecurityManager for java Rmi Registry
        System.setSecurityManager(new java.rmi.RMISecurityManager());
        if (b){ //Not First Program
            try{
                // Testing Line, outprint members entry of self
                System.out.println(members.get(0).toString());
                // Lookup RMI Registry name that is passed
                bankFace = (bankAccountFace) Naming.lookup("rmi://localhost:1099/"+cmd);
                // Retrive bankAccount refernce from the Interface class
                members.add(bankFace.getAccount());
                // Add bankAccount refernce to the list of members
                addMember(bankFace.getAccount());
                // Testing Line, outprint the newly aquired refernce of bankAccount
                System.out.println(members.get(1).toString()); 
                // Start ID at 1 (second proram)
                id = 1;  
            }catch(Exception e){ // Any problem
                System.err.println("Problem: " + e); 
            }
        }else{ //First Program
            try{
                // Register this object in the Rmi Registry naming service as
                // "BankServer_1"
                Naming.rebind("BankServer_1", this);
                // Testing Line, outprint members entry of self
                System.out.println(members.get(0).toString());
                // Start ID at 0 (first program)
                id = 0;
            }catch(Exception e){ // Any problem
                System.err.println("Problem: " + e); 
            }
        }
    }

I have narrowed down the problem to what I think is me trying to get a refernce of an object from itself that implements interface through the interface object that is regiesterd in RMI, however when I attempt to do this I receive the ClassCastException error.

(I apologize for the large block of code but wanted to make it clear as possible)
