Hello everyone. I've been trying to create beans from Java3D enabled objects. Unfortuantely, I cannot save the individual beans. Ususally I get an error of the form CanvasViewCache not Serializable error. I have tried using the Externizable class, but that generates other problems. For example, it will allow me to save, but then I cannot load. The error I receive is: java.io.InvalidClassException: MainAppClass; IllegalAccessException Does anyone have any experience with this task? Any suggestions or a working code fragment would help. =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
