Java EE (Java Enterprise Edition) General Discussion

I have a strange problem. I tried the Sample code for JSF component ui:table that uses a TripDataProvider. Here is the sample code

package com.kbs;

import com.sun.data.provider.impl.ObjectListDataProvider;
import java.util.ArrayList;
import java.util.Set;

public class TripDataProvider extends ObjectListDataProvider{
    private ArrayList tripsList = new ArrayList();
    
    /** Creates a new instance of tripDataProvider */
    public TripDataProvider() {
	
        // Put in dummy data for design time
        tripsList.add(new Trip()); 
		
      // Wrap the list
        setList(tripsList);
    }
    
    public void refreshTripsList(Integer personId){
        tripsList.clear();
    }
}

The Trip is a simple bean class with some attributes, getters and setters. Pls note the package com.kbs in the TripDataProvider. I added a property of TripDataProvider in the SessionBean1.java. When I go to my Page1 design and right click on my table and bring up the Table Layout, I dont see the tripDataProvider in the drop down list.

However, If I change the package of my classes from com.kbs to just kbs, then everything works fine and I can select this data provider. Could someone pls help me identify the problem. I have created new projects and tried several times to understand the problem but I have no clue about its solution.

thanks

By the way I am referring to the JSF Hibermate tutorial at

http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/hibernate.html

It has a TripDataProvider.

From the project that works fine, If I copy the JSP source about that table into the other project which has the problem, there is a PropertyNotfound exception for trip where trip is defined as a property in SessionBean1 as TripDataProvider. However, If i declare another property of type String, it is easily recognizable but not trip. I checked my managed-beans.xml also, it is allright.
