I\'m trying to use Hibernate to persist a class that looks like this:
public class Item implements Serializable, Comparable- {
// Item id
private
If it can help someone:
In my case there were errors in my mapping files. Classes were not referenced by their full package names. I did this mistake because I generated the mappings when my bean classes belonged to the default package (hence no package name; e.g.: Order instead of com.mypackage.Order) and then I moved my bean classes to package (in the example com.mypackage). Unfortunately mapping files did not changed accordingly with the new package definition.
My hint is redo Hibernate reverse engineering and see what it produces, comparing it with your current mapping files.
