[java] Saving in a Java Applet

Quote:

Original post by Limitz One problem with storing the files server side though is that you don't know what file belongs to what user. So they should have some sort of username/password to save, or you should provide them with a code they need to enter as soon as they want to continue playing. Furthermore you should probably save the gamestate in a database (which can easily be done in php, that is if you have a database). That will keep it more organized and it is easier than opening files on the server, since the usermode that php is running in usually doesnt have access to your folders (in which case you need to make an ftp connection to chmod a directory to 777 and write your file and chmod it again to 755 or whatever ,which is considered a hack) Greetings.

public class SaveGameServer implements Runnable {   public void run() {      Socket inComing = null;      while( (inComing = myServerSocket.accept()) != null ) {         Thread handleRequest = new Thread( InComingRequest( inComing ) );         handleRequest.start();      }   }}public class InComingRequest implements Runnable {   public void run() {            Object inComing = null;      try {         inComing = myObjectInputStream.readObject();         GameState gs = (GameState)inComing;         String code = gs.getSaveCode();         GameStore.savedGames.put( code, gs );         myObjectOutputStream.writeObject(code);      }catch( ClassCastException cce ) {         try {            String code = (String)inComing;                     GameState savedGame = (GameState)GameStore.savedGames.get(code);            myObjectOutputStream.sendObject(savedGame);         }catch( ClassCastException cce2 ) {                throw new InvalidRequestException();         }      }   }  }public class GameState {   //...All the current game state information   }public final GameStore {   public static HashMap savedGames = new HashMap();}

Original post by eat2thepieseye 5MinuteGaming, I've got a few questions about that code. First off, what is myServerSocket. Is that a new ServerSocket or something else? Also, what are myObjectInputStream and myObjectOutputStream? You also have the line "throw new InvalidRequestException();". Whats a InvalidRequestException(); and why do I need to throw it? Thanks for the help/ideas everyone. I think I'm going to get this to work.
