Hi all; i'm using JDom 1.0,  Jaxen version 1.0-FCS ( jaxen-full.jar ) on JBuilder2005.
I have this xml file called structure:

<?xml version="1.0" encoding="ISO-8859-1"?>

        <page name="Siti Tematici" id="FWD-001-005-001" descr="Ciao da angelo" jsPageName="HOME_SitiTematici">

      </page>
    </page>
  </site>
</site_structures>

I have this code:

public class Parser {

    private Map sites = new Hashtable();
    public void LeggiXML(String xmlFile, String pageId) {

        try {
            System.out.println(pageId);
            SAXBuilder builder = new SAXBuilder();
            Document document = builder.build(xmlFile);
            XPath xp = XPath.newInstance("/site_structures/site");
            Object el = XPath.selectSingleNode(document,"//page[@id='" + pageId + "']/../@name");
            System.out.println(el);
            //getPageKeys(pageId);
        } catch (JDOMException j) {

            j.printStackTrace();
        } catch (IOException ex) {

            ex.printStackTrace();
        }

    }

    public static void main(String[] args) {
        (new Parser()).LeggiXML("structure.xml", "FWD-001-005-001");
    }
}

Well when i try this code i have this error:
java.lang.NoSuchMethodError: org.jdom.Element.getParent()Lorg/jdom/Element;
	at org.jaxen.jdom.DocumentNavigator.getParentAxisIterator(DocumentNavigator.java:252)

	at site.Parser.LeggiXML(Parser.java:56)
	at site.Parser.main(Parser.java:70)
Exception in thread "main" ;

if i use this code:

public class Parser {

    private Map sites = new Hashtable();
    public void LeggiXML(String xmlFile, String pageId) {

        try {
            System.out.println(pageId);
            SAXBuilder builder = new SAXBuilder();
            Document document = builder.build(xmlFile);
            XPath xp = XPath.newInstance("/site_structures/site");
            Object el = XPath.selectSingleNode(document,"//page[@id='" + pageId + "']/@name");
            System.out.println(el);
            //getPageKeys(pageId);
        } catch (JDOMException j) {

            j.printStackTrace();
        } catch (IOException ex) {

            ex.printStackTrace();
        }

    }

    public static void main(String[] args) {
        (new Parser()).LeggiXML("structure.xml", "FWD-001-005-001");
    }
}

All works very fine;how can i avoid this error?
Thanks
