Method to return list of info from derby

[Jason Flaherty]

HI all, I am new here and working through a simple app. So forgive my ignorance. I am not finding an answer searching the forums.

I have a Derby db setup, I've used Hibernate to automate some of my setup. I am trying to create a Struts2 Select list with information from one of the columns, Usernames, in the db. I have this declared:

private List<TimesheetUser> _users;

and have:

    public void setUsers(List<TimesheetUser> users) {
		_users = users;
	}
	public List<TimesheetUser> getUsers() {
		return _users;
	}

My method where I am trying to get the users to call in my struts2 XML file is:

    public String showUsernames(){
    	TimesheetUserDAO su = new TimesheetUserDAO();
    	Session session = su.getSession();
    	//HERE IS MY ISSUE... how to do I find just my usernames?
        _users.
    	session.close();
    	return SUCCESS;
    }

If you need more code, let me know.
Thanks for any thoughts.
