refers to an unmapped class exception while running hibernate on your app?
Here is a solution
Mostly it would be related to the hbm file of the table that it is complaining. On that hbm file, make sure if you have the class attribute on the option properly addressed like if you haven’t added the package on the top, make sure you provide the FQN of the class.
Also make sure if the hbm file is listed on the hibernate.cfg.xml/ where ever the list of the hbm files are listed.
