javax.persistence.PersistenceException: org.hibernate.MappingException: Repeated column in mapping for entity: com.xxxx.xx.pojo.service.ServiceEntity column: value (should be mapped with insert="false" update="false")

I understand this error except that I don't have a column called 'value'. Is 'value' a placeholder for some column? This same error is thrown in more than one entity.

I have undone the changes I made before I got this error but the error still appears. I would be very grateful if someone would explain to me what 'value' is.

Thanks
