    Question HIERARCHY_REQUEST_ERR: An attempt was made to insert a node where it is not permitted

    Dear all members

    I am getting this error when i try to insert a new element(record) into my existing xml file.

    XML File:

    <User ID="1">

    <User ID="2">
    Java Code:
    Document xmlDomObject = parseXMLDocument();

    Node rootNode = xmlDomObject.getDocumentElement();

    Element userElement = xmlDomObject.createElementNS(null, "USER");
    userElement.setAttribute("Name", userName);

    // Create Child element for User Name.
    Element userNameElement = xmlDomObject
    .createElementNS(null, "UserName");
    Node userNameElementNode = xmlDomObject.createTextNode(userName);

    // Create Child element for User Name.
    Element roleElement = xmlDomObject.createElementNS(null, "Role");
    Node roleElementNode = xmlDomObject.createTextNode(Role);


    DocumentFragment documentFragment = xmlDomObject.createDocumentFragment();

    rootNode.insertBefore(documentFragment, tFirstChild().getNextSibling());//or use this -->rootNode.getChildNodes().item(1));

    xmlDomObject.appendChild(rootNode);//HERE I AM GETTING THE BELOW ERROR

    // Start Serialization Process using Serializable interface method - writeObject.
