What Would the Transfer Object Look Like If I Have a List of Objects

[Caroline Jen <ji...@yahoo.com>]

What would the "transfer object" look like If I have a
List of objects and each object has its properties? 
Do I have a HashSet in my transfer object?

To clarify my question, let me give an example.  
Say, I have a store and I sell music CDs.  Each CD has
composer, title, and price as its properties.  How do
I code the transfer object to pass data between J2EE
tiers?

In my JSF backing bean, I have java.util.List and I
use DataModel to display all CDs in tabulation:

import java.util.ArrayList;
import java.util.List;
import javax.faces.model.DataModel;
import javax.faces.model.ListDataModel;

public class CDManagerBean 
{
	private String title;
	private Float price;
	private String artist;

	private List cds = new ArrayList();
	private DataModel cdModel = new ListDataModel();
	
	{
		cdModel.setWrappedData(cds);
	}

                // getters and setters
                // addCD(), editCD(), and updateCD()
methods
}

I also have a CD java class:

public class CD implements java.io.Serializable
{

	private String title;
	private String artist;
	private float price;
	
	public CD(){}

                // getters and setters
}
