Hi, I'm making a message board system with Java Servlet. The servlet save all messages sent by clients into a file as Object with ObjectInputStream. but sometimes I get an error, and all information in the file is gone. The Error says "Local class not compatible: stream classdesc serialVersionUID=-6276226423314623654 local class serialVersionUID=-2865528740498031919". The servlet calld Message class that I made implements serializable. (The Message class will be saved into the file) If I change the Message class, No wonder the error comes up. but since I haven't changed the Message class...it's weird. It does NOT ALWAYS happen, but sometimes. It'll be critical. anyone knows what's going on with it ? ps) I change the servlet code, but Message class. Thanks in advance.
