I'm not sure how to fix the below exception. My datasource is injected into the sessionfactory and used by the DAO to create queries. My database is working perfectly fine considering other modules of the application are working fine. This makes me suspect that my model class 'Shopping' is wrong in some way. Is using java.sql.blob the incorrect way to represent a long blob in mysql database?
