if you dont want that BigDecimal to be serialized you may mark it with "transient"

for example:
public class YourClass implements Serializable{
   private transient BigDecimal myDecimal;


but if you need to serialize that instance variable, you should put two following methods in your class definition and customize serialization:

private void writeObject(ObjectOutputStream os) {
try {
} catch (Exception e) { e.printStackTrace(); }

private void readObject(ObjectInputStream is) {
try {
myDecimal = BigDecimal.valueOf((is.readDouble()));
} catch (Exception e) { e.printStackTrace(); }
