SetNodeValue() method does not work...

Dear experts,
 
I am newbie to Xerces, therefore my question might be stupid, but I'd appreciate your commenst very much :
 
I want to create a parent and childe xml nodes with values :
 
<element-1>
          <element-2> value </element-2>
</element-1>
 
That is my java program : 
 
 
import org.w3c.dom.*;
import javax.xml.parsers.*;

public class Aaa 
{
 
 public static void main(String[] args)
 {   
  
  DocumentBuilder db =   org.apache.soap.util.xml.XMLParserUtils.getXMLDocBuilder();

  Document doc = db.newDocument();
  
  Element e = doc.createElement("element-1");

 e.appendChild(doc.createElement("element-2"));
       
 e.getLastChild().setNodeValue("value");
                  
 System.out.println(e.getLastChild().getNodeValue());
 }   
}
 
So when I use method e.getLastChild().getNodeValue() it returns null as I understand method setNodeValue("value") did not set the value to the last node <elemet-2>
 
Could you please help me understand what I do wrong.
 
Thanks a lot in advance.
 
Jonas

I tried the first way :
 
1. Using DOM Level 1 interfaces, only:

Element e = doc.createElement("element-1");
Element e2 = e.appendChild(doc.createElement("element-2"));
e2.appendChild(doc.createTextNode("value"));

but I am not sure I've got the right result : 
 
<element-1>
         <element-2> value </element-2>
</element-1>
 
because server to which I sent this xml (as SOAP header) responded with the same error as I do not send the header at all - the required header is not found... 
 
Is it possible somehow to make visible sure that the Element e2 is of requierd structuer : 
 
<element-1>
         <element-2> value </element-2>
</element-1>

 
Thank you a lot :)

If you follow the spec 
<http://www.w3.org/TR/DOM-Level-3-Core/core.html#ID-F68D080>:

> nodeValue of type DOMString
>     The value of this node, depending on its type; see the table

The "table above" defines:

> Interface | nodeValue
> ----------+-----------
> Element   | null

What you want could be achieved both ways:

1. Using DOM Level 1 interfaces, only:

    Element e = doc.createElement("element-1");
    Element e2 = e.appendChild(doc.createElement("element-2"));
    e2.appendChild(doc.createTextNode("value"));

2. Using the DOM Level 3 'Node.textContent' [1]:

    Element e = doc.createElement("element-1");
    Element e2 = e.appendChild(doc.createElement("element-2"));
    e2.setTextContent("value");
