Hi Shakila, First error is more like deserialization issue. The "InvalidClassException" usually occurs when the receiver has loaded a class for the object that has a different serialVersionUID than that of the corresponding sender's class.
Have you defined explicitly "serialVersionUID" in your serializable class "TiqrAuthenticator"? If you do not explicitly declare this, serialization runtime will calculate this based on the various aspect of the class. According to the java doc[1], recommended way is to explicitly declare serialVersionUID values, since the default serialVersionUID computation is highly sensitive to class details that may vary depending on compiler implementations, and can thus result in unexpected InvalidClassExceptions during deserialization.
