I tell you, I have the following:
I have a small error when it comes to serializing them, mark that they are not serializable. Is there any chance that they can be serialized?
Thanks
If possible, you only have to make the classes / subclasses you want to serialize implement the Serializable interface, for example:
public class MiClase implements Serializable
{
}
The serializable interface does not have any methods so you should not worry about implementing methods.
