Newbie: how to use validate<attributeName> with D2W Application

I'm trying to use validate<attributeName> method with a D2W Application and have been unsuccessful so far. I am trying to update a "lastModified" NSTimestamp attribute in a product entity of my EO Model. My goal is to have the attribute updated to the current time every time a product object is modified. After doing some searching through the archives I created the following Product .java class file in the project:

// Product.java
// Created on Tue Aug 10 13:05:46 US/Eastern 2004 by Apple EOModeler Version 5.2


import com.webobjects.foundation.*;
import com.webobjects.eocontrol.*;
import java.math.BigDecimal;
import java.util.*;

public class Product extends EOGenericRecord {

    public Product() {
        super();
    }

	public void awakeFromInsertion(EOEditingContext editingContext) {
        super.awakeFromInsertion(editingContext);
        setProductType(entityName());
    }

    public String productType() {
        return (String)storedValueForKey("productType");
    }
    public void setProductType(String value) {
        takeStoredValueForKey(value, "productType");
    }

	public NSTimestamp lastModified() {
		return (NSTimestamp)storedValueForKey("lastModified");
	}
	public void setLastModified(NSTimestamp value) {
		takeStoredValueForKey(value, "lastModified");
	}
	public NSTimestamp validateLastModfied(NSTimestamp value) {
		return new NSTimestamp();
	}
}



However... it is still not working correctly any help greatly appreciated
