JavaFX application with JDBC in NetBeans don't start

I work on a small educational project - easy java app with database and gui. I work in NetBeans IDE.
For graphical interface I use JavaFX, and as I've testet this part work perfectly fine, but I have some problem with JDBC part (I use JDBC driver for sqlite database, created with DB browser for sqlite). My main application class looks like this:
public class BazaLyoko extends Application {
#Override
public void start(Stage stage) throws Exception {
Database baza = new Database();
String tytul = baza.getEpisodeName(1);
stage.setTitle(tytul);
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) {
launch(args);
}
}
And when I change those lines:
Database baza = new Database();
String tytul = baza.getEpisodeName(1);
To this (to replace value retrieved from database to a placeholder - I did this to ensure if the error is rather connected with JavaFX or JDBC part)
String tytul = "";
Program start without problem, but when I try to use my database application don't start. There isn't any compilation error or anything like that (or maybe I just don't see them, as I'm quite new to this IDE, though I think such things are usually blatantly visible) just no application window appear.
Here's the code for my database class(they both share the same package):
public class Database {
public static Connection conn;
public Database()
{
connect();
}
public static void connect()
{
String connectionString = "jdbc:sqlite:BazaLyoko.db";
try
{
conn = DriverManager.getConnection(connectionString);
if (conn != null)
{
DatabaseMetaData meta = conn.getMetaData();
//System.out.println("Nazwa sterownika to " + meta.getDriverName());
//System.out.println("Stworzono baze danych.");
}
}
catch (SQLException e)
{
System.out.println(e.getMessage());
}
}
private ResultSet doQuery(String query) throws SQLException
{
Statement stmt = null;
try
{
stmt = this.conn.createStatement();
ResultSet result = stmt.executeQuery(query);
return result;
}
catch (SQLException e )
{
throw new Error("Problem", e);
}
finally
{
if (stmt != null) { stmt.close(); }
}
}
public String getEpisodeName(int nr) throws SQLException
{
ResultSet result = doQuery("SELECT tytul FROM Odcinki WHERE numer="+String.valueOf(nr));
result.next();
return result.getString("tytul");
}
}
Database of that name is located inside my project directory (i also tried to copy it to package directory but nothing changed), the names of the table and column are correct to and exist a row with value 1 in column numer.
What I'm missing or doing wrong?
Edit:
I manage to get the following Stack Trace:

Why do I get ClassNotFoundException when I call it from outside class? [duplicate]

This question already has answers here:
How to install JDBC driver in Eclipse web project without facing java.lang.ClassNotFoundexception
(13 answers)
Closed 6 years ago.
Below is the code that works perfectly fine when it is executed from main (ie in eclipse RunAs java application). However if I call Statement getStatement from outside ( meaning a servlet calling it via a put ) in the same package I get java.lang.ClassNotFoundException: com.mysql.jdbc.Driver. Any pointers to why ?
public class DBConnectivity {
private static Statement getStatement(String username, String password) throws SQLException, ClassNotFoundException {
Properties prop = new Properties();
prop.put("user", "root");
prop.put("password", "password");
Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/keeptrack", prop);
Statement stmt = conn.createStatement();
return stmt;
}
public void put(String username, String password, String table,
String name, String exercise, String wsj, String food)
throws SQLException, ClassNotFoundException {
Statement stmt = getStatement(username, password);
// checkIfTableExists(stmt, table);
stmt.executeUpdate(
"insert into " + table +
" " +
"values(\'" + name + "\', \'" + exercise + "\', \'" + wsj + "\', \'" + food + "\')");
}
public List<String> get(String username, String password, String table)
throws SQLException, ClassNotFoundException {
Statement stmt = getStatement(username, password);
//checkIfTableExists(stmt, table);
ResultSet rs = stmt.executeQuery("select FOOD from " + table);
List<String> foodData = new ArrayList<String>();
while(rs.next()) {
String output = rs.getString("FOOD");
foodData.add(output);
// System.out.println("wohoo: " + output);
}
return foodData;
}
public static void main(String[] args) throws SQLException, ClassNotFoundException {
DBConnectivity conn = new DBConnectivity();
conn.put("root", "password", "trackTable", "D", "B", "C", "D");
conn.get("root", "password", "trackTable");
}
}
Here is the servlet which calls the database:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String username = request.getParameter("firstname");
String password = request.getParameter("lastname");
String firstname = username;
String exercise = request.getParameter("exerise");
String wsj = request.getParameter("wsj");
String food = request.getParameter("food");
try {
new DBConnectivity().put(username, password, "trackTable", firstname, exercise, wsj, food);
} catch (ClassNotFoundException | SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
The new DBConnectivity().put call results in ClassNotFoundException.
Stack trace is :

Your error:
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
If it works running from Eclipse, that means you have the MySql jdbc dirver jar in the classpath of your project, but it is not available to your web application.
The project class path (build path) is not the same as the class path of your web application when deployed. Not all jars being on your project class path get exported automatically.
Usually jars in the WEB-INF/lib will be available for the web application, but jars outside of that will not.
You should either place the MySql jdbc driver jar in WEB-INF/lib, or add it to the lib folder of your Servlet container (Tomcat in your case judging by the exception stack trace).

You have to include mysql-connector-java-5.1.24-bin.jar library file into your project.
Then it will not give the error class not found.
this file located inside C:\Program Files\MySQL\Connector J 5.1.20.0 folder.

Add mysql-conneter jar in your project library. You can download it from below link
Download Connector Jar file

make sure that the packager you are using for creating war file (it could just as well be eclipse), is putting the mysql driver jar file in the war's web-inf lib.
typically, in eclipse you ensure above by going to project properties->deployment assembly and making sure your driver jar is included

If you execute the same method (main) in other class inside the project, must be executed perfectly.
The classloader is the same, but you can't access to the method getStatement outside the class DBConnectivity because the method is private.
You could execute this method by reflection.

java.rmi.NoSuchObjectException but static reference added

i'm implementing a client/server app with java RMI, client and server are in different packages in the same project (and of course they run on the same machine) and interfaces are defined in a "common" package.When i try to get one of the two remote object i get the aforementioned excepition. I've read some SO answers where people sugget to add a static reference to remote object so they can be never collected, but this doesn't work!
here is the code of the client and server
NotificheServiceProxy
public class NotificheServiceProxy implements INotificheService
{
#Override
public ArrayList <NotificaDTO> generaNotifiche(String autostrada, Date data, Date oraInizio, Date oraFine)

INotificheService service = (INotificheService) client.getService(INotificheService.class);
return service.generaNotifiche(autostrada, data, oraInizio, oraFine);
}
catch (RemoteException ex)
{
Logger.getLogger(TrattaServiceProxy.class.getName()).log(Level.SEVERE, null, ex);
return null;
}
catch (NotBoundException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
}
RMIClient
public class RMIClient
{
private Registry reg;
public RMIClient (String url , int port) throws RemoteException
{
reg = LocateRegistry.getRegistry(url, port);
}
public Remote getService(Class service) throws NotBoundException, RemoteException
{
RMIMapping RMIMappingAnn = (RMIMapping) service.getAnnotation(RMIMapping.class);
return reg.lookup(RMIMappingAnn.name());
}
}
NotificheService (server side)
public class NotificheService implements INotificheService
{
private static NotificheService instance;
#Override

return new NotificheBusinessLogic().generaNotifiche(autostrada, data, oraInizio, oraFine);
}
}
scServerConfig (server main)
public class SCServerConfig
{

public static void main (String[] args)
{
server = new RMIServer(1099);
//avvia il server ed esporta oggetti remoti
server.start().export(TrattaService.class).export(NotificheService.class);
//Other stuff
RMIServer (starts server and provide method for remote objects exporting
public class RMIServer
{
private Registry reg;
private int regPort;
public RMIServer (int regPort)
{
this.regPort = regPort;
}
public RMIServer start()
{
try
{
reg = LocateRegistry.createRegistry(regPort);
System.out.println("SERVER OK");
}
catch (RemoteException ex)
{
Logger.getLogger(RMIServer.class.getName()).log(Level.SEVERE, null, ex);
}
return this;
}
public RMIServer export (Class object)
{
try
{
RMIMapping RMIMappingAnn = (RMIMapping) object.getInterfaces()[0].getAnnotation(RMIMapping.class);
Remote tmp = UnicastRemoteObject.exportObject((Remote)object.newInstance(), 0);
reg.rebind( RMIMappingAnn.name() , tmp );
System.out.println("oggetto remoto esportato " + object);
}
catch (InstantiationException ex)
{
System.err.println("InstantiationExeception!!\ncause:\n 1. il costruttore dell' oggetto remoto non deve avere argomenti");
}
catch (IllegalAccessException ex)
{
Logger.getLogger(RMIServer.class.getName()).log(Level.SEVERE, null, ex);
}
catch (RemoteException ex)
{
Logger.getLogger(RMIServer.class.getName()).log(Level.SEVERE, null, ex);
}
return this;
}
}
Each interface is annotated with #RMIMapping annotation that provides the object binding name. But i'm sure that the problem doesn'come from this
This is for me a real mistery, this is the stacktrace......many thanks for help!

EDIT: #EJP before that, i've done something like
public class RemoteObject implements IRemoteObject
{
private static RemoteObject instance;
public RemoteObject ()
{
instance = this;
}
public someType someMethod (...)
}
but it throwed the same exception. Furthermore, as you can see, in scServerConfig there is a
public static RMIServer server;
which encapsulates a Registry reference. if these thing i've done are correct, i think that adding static references may not be enough, even tough "suddendly" started to work for me. Am I wrong?

java.rmi.NoSuchObjectException but static reference added
It isn't added. You're trying to call the remote method that adds it. You're failing at that, so it hasn't hapoened yet.
You need to set the static instance in the constructor of your remote object. Doing it in the remote method may already be too late.
I suggest you also keep the Registry in a static variable server side. In fact strictly speaking that's the only reference you need to keep static.

I'm trying to costumize a Synthetica theme in netbeans as this article shows :
http://www.jyloo.com/news/?pubId=1335947397000
So, I created the costum.xml file and I added it to my project folder as : /home/aimad/NetBeansProjects/GestionStock/costum.xml
and I create this code in my Form constructor :
public PersonelMainForm() {
try {
try {

loadXMLConfig("custom.xml");
}
});

}
} catch (ParseException ex) {
Logger.getLogger(PersonelMainForm.class.getName()).log(Level.SEVERE, null, ex);

I've just tried running the sample java files that I got with the epson tm-t20 printer that I bought. These classes should run but they keep giving me errors. I've been looking at this for over 8 hours now I'm really getting frustrated. This is the exception it's throwing at me:

try {
jbInit();
}
catch(Exception e) {
e.printStackTrace();
}
}
/**Form the component*/
private void jbInit() throws Exception {
//setIconImage(Toolkit.getDefaultToolkit().createImage(Step1Frame.class.getResource("[Your Icon]")));
contentPane = (JPanel) this.getContentPane();
titledBorder1 = new TitledBorder(BorderFactory.createEtchedBorder(Color.white,new Color(134, 134, 134)),"Receipt");
contentPane.setLayout(gridBagLayout1);
this.setSize(new Dimension(300, 180));
this.setTitle("Step 1 Print \"Hello JavaPOS\"");
jPanel_reciept.setLayout(gridBagLayout2);
jPanel_reciept.setBorder(titledBorder1);
jButton_Print.setText("Print");
jButton_Print.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
jButton_Print_actionPerformed(e);
}
});
contentPane.add(jPanel_reciept, new GridBagConstraints(0, 0, 1, 1, 0.0, 0.0

You have to put some additionally dependency library to the project classpath, one of them seems to be the apache xerces XML parser, so basically you have to add that jar library to the classpath .
you can find the apache xerces XML parser here .

For me class org/apache/xerces/parsers/DOMParser is missing. You can download it from maven repository xercesImpl.jar
