How do you re-display a JTree node?

I am using Java Swing v2 by Robinson & Vorobiev as a framework to understand JTree's. I have redone the source code from [https://www.manning.com/books/swing-second-edition][1] Chapter17/4 to include better encapsulating and information hiding. The rename EditorListener (CellEditorListener) had a bug in that java.io.File.rename() did not work but java.nio.Files.move() does. I then included checks for an existing directory and for a failure to move.
The issue is that in these two failures the only thing needed is to update the GUI so that the original value of the node is displayed. The node data does not change and does not need to be updated. The display area update I know how to do. But I do not know how to update only the displayed node. The only thing that seems to work is to replace the tree node with a new version of itself.
Code is below. Any help will be greatly appreciated.

CmisObjectNotFoundException when trying to access my Alfresco repository

I'm new with CMIS and Alfresco and I got this error when in try to connect to my Alfresco's repository using AtomPUB binding. I have no idea about the source of my problem. Is it unless a functionality ? Is it my Credential ?
When I install it, I choose only :
- Alfresco community
- Solr4
How should I do if I want to use web services ? Should I install a specific plugin in my Alfresco ?
I got with error :

I found the solution, it's because of Alfresco's version. Since the V4.x the url of the AtomPUB is http://localhost:8080/alfresco/cmisatom.

Instance "Main" Method Not Running When Called from Another Class

I'm learning Java and experimenting with Javafx in netbeans.
I am running the sqlite tutorial here: http://www.tutorialspoint.com/sqlite/sqlite_java.htm
When set up as a lone-file it works fine of course.
I'm setting it up in a test project "testDB" and for some reason when I initiate the class the class itself is recognized, but main() is not running.
Here is the testdb file itself:
testDB.java:
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package sqlitetest;
import java.sql.*;
/**
*
*/
public class testDB {
public static void main(String args[]) {
//THESE STEPS ARE ON NOT RUNNING (compiles without errors)
System.out.println("testing");
Connection c = null;
try {
Class.forName("org.sqlite.JDBC");
c = DriverManager.getConnection("jdbc:sqlite:test.db");
} catch (Exception e) {
System.err.println(e.getClass().getName() + ": " + e.getMessage());
System.exit(0);
}
System.out.println("Opened database successfully");
}
public void makeStuff(){
}
}
sqlitetest.java
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package sqlitetest;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
/**
*
*/
public class Sqlitetest extends Application {
#Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
testDB test = new testDB();
test.makeStuff();
launch(args);
}
}

I think you are getting confused between a constructor and a main method.
A main method is only invoked when you start the JVM, running that specific class (or if you invoke it explicitly elsewhere).
A constructor is invoked when you create an instance of the class, like you are doing here.
In testdb, change:
public static void main(String args[]) {
to
public testdb() {
Alternatively, invoke testdb.main(args) (or with some other parameter) in Sqlitetest.main.

Page Expiration in Java(Wicket)

I'm writing a wicket project for a social network.In my project i have authentication so when a user enter address of the home page he is redirected to login page in this way:
public class MyApplication extends WebApplication {
private Folder uploadFolder = null;
#Override
public Class getHomePage() {
return UserHome.class;

in this situation i have a googlemap in one of my protectedpage and because googlemap needs to read data for loading builing from a xml so i create a servlet which will create it dynamicly depending on the Username. this servlet is below:

I have made this page at first protected and so the user had to loged in to have access this xml but after lot's of debuging i found that googlemap can't log in my system so instead of parsing the dataxml it pars login page html az input. so i changed the extention of the CategoriesXML to extend WebPage.
But now I have another problem:
When i go to the google map page in my Social site I can Not refresh the page because It expires and so I cannot add another building to my data xml.
what should I do?
tell me if you need more code or information

In trying to close this question, which the OP seems to have pretty much abandoned, I'll just post my old comment as an answer..:
In your CategoriesXML I would highly advise against building and adding your tags as Strings and adding them to pages just like that. See if you can work this into a in your .xml(?) file instead, as that's the Wicket way to do things (and as such just might solve the problems you're having)

Would making this WebPage extends org.apache.wicket.Page instead and associate the markup to return as xml instead of html? Basically, mimicking a WebPage, but implementing it for XML.
