Hermod -----Opprinnelig melding----- Fra: Gareth Evans [mailto:[EMAIL PROTECTED] Sendt: 8. september 2005 10:54 Til: Struts Users Mailing List Emne: Re: Exception after File Upload. Because when you shutdown tomcat, it tries to serial all objects within the session scope. The class you are referring to 'org.apache.commons.fileupload.DeferredFileOutputStream' does not implement 'java.io.Serializable' and therefore tomcat throws this exception when trying to serialize it. Whilst I don't know what the class 'org.apache.catalina.session.StandardManager' does, presumably is performs a check to see if an object stored within the session is serializable before trying to write it disk, or it might remove non-serializable object from the session scope on shutdown.
