    Default write & read/load to/from file

    Hello, I need to write some objects to a file, then when I 'read' them back to the program, they have to be exactly the same, they have to be the same kind of objects, with the same name and everything, I have tried several different approches, but it all fails, the objects are 'accounts' for a bank (run over rmi)

        	AccountServer KAC= new AccountServer("Jane");
        	AccountServer JAC = new AccountServer("John");
     
        	Naming.rebind("Jane",KAC);	
        	KAC.setName("Jane");
        	KAC.setNumber(1234);
        	KAC.setBalance(600);
     
        	Naming.rebind("John",JAC);
        	JAC.setName("John");
        	JAC.setNumber(2345);
        	JAC.setBalance(50);

    The important thing here is the 'Naming.rebind' is has to become "Jane"/"John" or whatever the name is, becouse the bank client finds the account using 'Naming'
    Any thoughts? I am loosing my mind here

    Can you post the code you have written to do this and explain what the problem with it is?

    Your coding does not follow standard java coding conventions: first letter of a classname should be uppercase, first letter of variable should be lowercase. What is Naming? classname of variable

    If you don't understand my answer, don't ignore it, ask a question.

    If your intention is to save the state of the object and read it again then serialization is the best way to do it. Save it using serialization and read it back by de-serializing
