NoSuchMethodError

All:
     I wrote very simple java is using parser read xml and output to "name,value" format,
     but I got   NoSuchMethodError this error. I added "w3cdom1.jar in my classpath". 
     Is that right jar file ? Please advise, thanks.

The folllowings are my java code:

import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import javax.xml.parsers.*;

                        System.exit(1);
                }
                try {
