Question

I did a small example program to insert data to a MySQL database table using java Hibernate. Every thing went fine & I got the result

“INFO: schema update complete
Hibernate: insert into items (itemcode, itemdiscription, itemprice, itemId) values (?, ?, ?, ?)
BUILD SUCCESSFUL (total time: 2 seconds)”

My mapping file & config file are OK.
But when I’m running the query in command prompt to fetch updated values it doesn’t show entered values by my java pojo class.
Why is that???
Please consider I have used netbeans 7.1 for this.

Mapping file

add these lines..
session =sessionFactory.openSession();
Transaction tx = session.beginTransaction(); //new line
Item item = new Item();



session.save(item);
 System.out.println("Done");
 tx.commit(); //new line
 }catch(Exception e){
