findbycriteria

Hi,

i am experimenting using Hibernate.

I am trying to get a User by id this is what i do

public User get(DetachedCriteria dc){
    List<User> users = getHibernateTemplate().findByCriteria(dc);
    if(users != null)
    {
        return users.get(0);
    }
    else return null;
}

but it fails when the user is not in the database. Could you help me to understand how to achieve this?

Thanks
