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

Is anybody tested for appendChild method

Thanks

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.
