Help with JTable ... ClassCastException

Show all headers | View raw

Hi all,

I'm writing a GUI to show a JTable cointaining data from a db table 
(after I'll add also buttons to Add, Update and Delete rows). I need to 
have different table fields and not only strings.

I've used Hibernate to do the select and then passed the list to a 
Vector containing ConfigPersonale objects (my table bean).

I get this exception running the GUI:
