how do i convert an hash map into a byte array(being able to restore
this later , without losing data)?Serialization !

can you send me link where to find out how? private static byte[] s=

erialize(Object o) throws IOException {

         ByteArrayOutputStream ba = new ByteArrayOutputStream(1000);
         ObjectOutputStream oba = new ObjectOutputStream(ba);
         oba.writeObject(o);
         return ba.toByteArray();
     }

     private static Object deserialize(byte[] b) throws IOException,
ClassNotFoundException {
         ByteArrayInputStream ba = new ByteArrayInputStream(b);
         ObjectInputStream oba = new ObjectInputStream(ba);
         return oba.readObject();
     }

All objects need to be serializable for this to work though !

thanks so much! I will try now!
