This sounds like you need to make sure that each server/node in the cluster has the same version of the class. The failover node is trying to deserialize a class that was serialized on the original node as a different version of the same class.

Hi All, I have an ActionForm that has a FormFile attribute used for fileupload. I had the attribute marked as transient so that the ActionForm can be serializable and replicate in a cluster environment. However, the out come is not what I am expected, it throws InvalidClassException. Does anyone know what happens or how to fix this?
