XML insert not happening in my code

[saravanan sambandam]

<?xml version="1.0" encoding="UTF-8"?>
<Menus>
<appMenu>
<mainMenu id = "1" name = "Home" alias = "home" uType = "a" status = "a" parentId = "0" orderBy = "1" width = "" img = "" link = "" >

<gSubMenu id ="" name = "" alias = "" uType = "" status = "" parentId = "" orderBy = "" width = "" img = "" link = "" />
</subMenu>
</mainMenu>
</appMenu>
</Menus>

public class A{
String fileName = request.getRealPath("/WEB-INF/MainMenu.xml");
File file = new File(fileName);
DocumentHandler dh = new DocumentHandler();
Document mainMenuDoc = dh.getDocument(file);
if(this.mainMenuDoc != null) { 
	NodeList rootList = this.mainMenuDoc.getElementsByTagName(AEMenuInterface.MAINMENU_ROOT_TAG);
	System.out.println("rootList length - " + rootList.getLength());
	Element rootEle   = dh.getElement(rootList);
	System.out.println("root Node name - " + rootEle.getNodeName());
	NodeList appList  = rootEle.getElementsByTagName(AEMenuInterface.MAINMENU_APP_MENU_TAG);
	System.out.println("AppList length - (parent List) " + appList.getLength());
	Element AppEle   = dh.getElement(appList);
	System.out.println("AppEle Node name - " + AppEle.getNodeName());
	parentElement = null;
	parentElement = AppEle;

	NodeList mainList = AppEle.getElementsByTagName(AEMenuInterface.MAINMENU_MAIN_MENU_TAG);
	System.out.println("mainList length - " + mainList.getLength());
	if(this.inp_parentId == 0) {
		Node cloneNode =  mainList.item(0);
		Element cloneElement = (Element)cloneNode;
		System.out.println("cloneElement name = " + cloneElement.getNodeName());

		
	    parentElement.insertBefore(cloneNode, parentElement.getLastChild());
		
		
		System.out.println("going to update now");
		Source source = new DOMSource(this.mainMenuDoc);
		Result result = new StreamResult(fileName);
		try {
			Transformer xformer = TransformerFactory.newInstance().newTransformer();
			xformer.transform(source, result);
		}catch (Exception e){
			e.printStackTrace();
		}

}
public class DocumentHandler{

	public Document getDocument(File fileName){		
		if(fileName.exists()){			
			try {
				DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
				DocumentBuilder db = dbf.newDocumentBuilder();
				this.Doc = db.parse(fileName);
			}catch(Exception e){
				System.out.println(this.getClass().getName()+ " - " + e.getMessage());
			}			 
		}else{
			System.err.println("File not found - " + fileName.toString());
		}
		return this.Doc;
	}


	public Element getElement(NodeList nodeList){
		if(nodeList != null) {
			this.element = (Element) nodeList.item(0);
		}
		return this.element;
	}
}

Input comes from jsp. If the parent id = 0 means it will be main menu otherwise it will be submenu. example. MenuName is "News" , parent id=0. In that case i need to clone from <mainmenu> tag and need to change the attributes and update with existng tree.

My case - clone and insert was not happening if any one found helps me it will be great help to me.

Thanks

Hi it was updating in my XML, but it not reflecting in my current workspace.

My problem is - i using RAD 7.5 and my mainmenu xml is "/WEB-INF/MainMenu.xml";but its updating here E:\Struts Project\Rad7.5\Version\ver_0.1\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\aeWebPortal\WEB-INF\MainMenu.xml.

Its not reflecting here in "/WEB-INF/MainMenu.xml".

Please tell me as soon as possible


Still its not working! what i need to change please tell me as soon as possible!

I see. So your RAD starts up a server, which is a separate process with a different directory structure. And you update an XML document in that server's directory structure. That looks like a fairly reasonable thing to do.

But what would be the point in having the server also update some file somewhere else? (That's the one in RAD which you thought would be updated.) In real life when you deploy your server, there isn't going to be a RAD environment anywhere on the machine.

Did you try running it outside of RAD (or for that matter, outside of any IDE)?
