Hello, i want to store objects in session, and for that I need to implements java.io.Serializable. The problem is that i don't know if i should generate the serialVersionUID field... My classes change from one deploy to another, so i get the exception InvalidClassException, because at first, the field serialVersionUID was not generated. If i generate that field for my superclass, will that solve the problem for all my classes that extends it ? Will there be a problem if the two classes are different but have the same serialVersionUID? What is the best thing to do here?
