It looks like you have a missing dependency (jar) in your web application.
Your application is configured such that your view state is being serialized between requests while your session is retained in memory between requests.
Java loads classes lazily. The act of serializing your view-scoped bean is causing the resolution of a class (JDOMException
) that is not required during normal execution of the type.
