Hi all, Any suggestion on my scenario? Error:

java.io.InvalidClassException: org.zkoss.util.media.AMedia; local class incompatible: stream classdesc serialVersionUID = -4259431189827860324, local class serialVersionUID = -5581038181341248556

local class incompatible: stream classdesc serialversionuid during updation of ZK6 to Zk8.6 Can not able to read my attachment due to serialversionuid.Is there any solution to deserialize?

You should store the file itself (images, pdf) instead of serializing ZK AMedia into the database.

  1. write a migration job in ZK 6, which read the AMedia from database, and get back the file
  2. store the files back into the database
  3. read the files in ZK 8
