NotSerializableException when sending an Object

Question

I want to create an instance , put it on a container and send it.

TransferContainer container = null;
    ...
  Class aClass = container.getByteCode();
    o = aClass.newInstance();
    ....// Some code
    ...
    container.setInstance(o);
    ObjectOutputStream out = new ObjectOutputStream(_s.getOutputStream());
    out.writeObject(container);

I get this error

java.io.NotSerializableException If I don't add the the instance o in the container I can send it without any problem.

The reason for this exception is that aClass or some instance field of aClass doesn't implement Serializable.

aClass can be any given class by the user , Class aClass = container.getByteCode(); – user567 Jul 11 '14 at 21:36
@user567 fine. But if u want to serialize it , its all instance fields must implement serializable or make them transient if they are not required otherwise this is expected error. – Vipin Jul 11 '14 at 21:44
@user567 Then your design is wrong. You can only allow classes that are Serializable. – user207421 Jul 11 '14 at 21:44
If it is some kind of API you are publishing then properly document it also so that user are aware of this fact before sending any class. – Vipin Jul 11 '14 at 21:45
