javax.persistence.PersistenceException: org.hibernate.type.SerializationException: could not deserialize

Question

When executing a Criteria Query in hibernate, I get the following exception:

javax.persistence.PersistenceException: javax.persistence.PersistenceException: org.         


        

Answer 1

I have my entity class UploadFiles having two fields as fid & fname where fid being primary key. I have my query in dao as

StringBuilder queryString = new StringBuilder("from UploadFiles f where f.fid=1");

Query query = (Query) session.createQuery(queryString.toString());          
return query.list();

when it execute query.list(),it gives serialization exception
