Hola a todos,
Estoy mejorando una aplicación y me he encontrado con un problema a mitad de camino.
Tengo la instancia de una clase que debo almacenar en una Oracle 9i para poder recuperarla de nuevo. La clase de guarda con el método writeObject() y se recupera con el readObject. Dentro de la clase, uno de los atributos es del tipo Date y cuando intento recuperarlo, me sale este error:
Código:
java.io.InvalidClassException: java.util.Date; local class incompatible: stream classdesc serialVersionUID = 7523895402267505689, local class serialVersionUID = 7523967970034938905

En algunos foros me han dado soluciones del tipo añadir la serialVersionUID a pelo, pero esto tampoco ha funcionado y ya empiezo a estar desesperado. Gracias
