    Posted Wed August 07, 2002 12:08 PM

    hello,

    I am tring to update the node in the existing document.

    This is source code
    <%@ page language=“java” import =“java.io." %>
    <%@ page import ="org.w3c.dom.
    ” %>
    <%@ page import =“javax.xml.parsers." %>
    <%@ page import ="com.softwareag.tamino.API.dom.
    ” %>
    <%
    TaminoClient tamino= null;
    try{
    System.out.println(“Ok”);
    File fin = new File(“test.xml”);
    DocumentBuilderFactory Dbf = DocumentBuilderFactory.newInstance();
    DocumentBuilder bd = Dbf.newDocumentBuilder();
    org.w3c.dom.Document md=bd.parse(fin);
    String QueryVal=“//root[login/username='shan’and login/password=‘thi’]”;
    Element ele = md.getDocumentElement();
    System.out.println(ele.getNodeName());
    Node newNode =md.getElementsByTagName(ele.getNodeName()).item(0);
    tamino=new TaminoClient(“http://localhost/tamino/tempa/data1”);
    tamino.startSession();
    TaminoResult tr3= tamino.query(QueryVal);
    Element item= (Element)tr3.getElement().getFirstChild();
    Node oldNode = item.getElementsByTagName(ele.getNodeName()).item(0);
    oldNode.appendChild(newNode.getChildNodes().item(0));
    TaminoResult tr1 = tamino.update(item);
    tamino.commit(true);
    }catch(Exception e){e.printStackTrace();}
    finally{
    tamino.endSession();
    tamino = null;
    }
    %>

    This is the error i am getting

    OK the appendChild method you are using is the DOM method and therefore this is a DOM problem !

    I see that you are using the old “HTTP Client for Java” which delivers DOM level 1 objects and xerces will probably deliver DOM level 2 objects. I think this is where the exception is coming from. I would suggest using the new “Tamino API for Java” which uses xerces and delivers DOM level 2 objects.
