It's not a case of an unknown reference causing the not serializable exception. I know which object is not serializable and it is the concrete proxy object created by WebLogic for my remote EJB. I ended up checking if I was in development mode and then using a transient variable and then using a another variable which is not transient when the app is running in a production environment. I was hesitant to simply mark the EJB as transient in case it caused issues in the production environment. Thanks all for your replies, they helped confirm that there wasn't a workaround other than marking it transient. Regards
