creating new Data Object for each client

[Yassine Lajmi]

Hi all,
I have a question concerning the rmi server :
do i have to create a new Data instance for each client or a single instance of data is Ok.
if yes how to do it.
thanks

Hi Lajmi,
I think that creating a new Data object for each client would definitely corrupt your db.db file. You shouldn't create more than one instance of the Data class.

thank you Kumar,
In this case how to be sure that a single instance of data was created for each client.
I have made a simple System.out.println in the constractor of Data, and for each Client it is printed.
i don't understend why a new instance is created.
in the server :
try{
Registry r = LocateRegistry.createRegistry(port);
database = new DataAccessImpl(dbFileName);
r.rebind(bindName, database);
}catch(Exception e){
System.out.println("Exception occurred on DataServer : " + e);
System.exit(0);
}
in the Client side :
System.setSecurityManager(new RMISecurityManager());
dataAccess = (DataAccess) Naming.lookup("rmi://"+serverDNS+":"+port+"/DataAcess_BindName");

u should use the factory pattern.
