Hello,

I'm using Netbeans with JDK 7. I'm developing a swing desktop application with embedded derby database.

I'm using the following code.

Statement stmt; try { Class.forName("org.apache.derby.jdbc.EmbeddedDriver"); Connection conn = DriverManager.getConnection("jdbc:derby://localhost:1527/HelloWorld", "userid", "password"); stmt = conn.createStatement(); String sql = "INSERT INTO TABLEEMP " + "VALUES (" + Integer.parseInt(jTextField1.getText()) + ", '" + jTextField2.getText() + "')"; stmt.executeUpdate(sql); JOptionPane.showMessageDialog(null, "Success"); } catch (Exception ex) { JOptionPane.showMessageDialog(null, ex.getMessage()); }

When i'm running this piece of code in Netbeans it's working fine. But when I close NetBeans and doubly click on the JAR file, it's throwing the following error:
java.net.ConnectException : Error connectiong to server localhost on port 1527 with message Connection refused : Connect

So, how to connect derby DB for distributed jar ?
How can i overcome this. Please help...

@Bear Bibeault : I've already posted(edited) the code above. Please check it.

@Rob Camick : I've posted SSCCE. Could you please test it ?

This is a single piece of code of my entire project. I'm stuck in this portion. That's why I've posted this portion. Please check this code & inform what's wrong with this.

@Rob Camick: Actually I did not get any solution from that post, and also I dont know what's wrong with the code. That's why I posted it here. Could you please help me out ?

Hello All,

I've a swing structure : JPopupMenu contains JPanel which contains JCheckBoxMenuItem. The problem is, I cannot use it because JPopupMenu disappears when mouse enters to any MenuItems.
I added JCheckBoxMenuItem to JPanel(because to make it scrollable, as there are large number of menu-items) and then JPanel to JPopupMenu.
I'm using NetBeans IDE.
Here is the code, done so far.

import java.awt.*; import java.awt.event.*; import javax.swing.*; public class PopupTest extends JFrame { JButton button1; public PopupTest() { setTitle("Popup Test !"); setSize(400, 400); setVisible(true); setDefaultCloseOperation(EXIT_ON_CLOSE); setLayout(new FlowLayout()); button1 = new JButton("Click me!"); button1.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { int count = 250; // this count value is dynamic JPopupMenu menu = new JPopupMenu(); JCheckBoxMenuItem item = null; JPanel panel = new JPanel(); panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS)); JScrollPane scrollPane = new JScrollPane(panel, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_NEVER); scrollPane.setPreferredSize(new Dimension(125, 200)); for (int i = 1; i <= count; i++) { item = new JCheckBoxMenuItem("Page : " + i, new ImageIcon("test.png")); item.setHorizontalTextPosition(JMenuItem.RIGHT); panel.add(item); } menu.add(scrollPane); if (!menu.isVisible()) { Point p = button1.getLocationOnScreen(); menu.setInvoker(button1); menu.setLocation((int) p.getX(), (int) p.getY() + button1.getHeight()); menu.setVisible(true); } else { menu.setVisible(false); } } }); add(button1); } public static void main(String args[]) { new PopupTest(); } }

Please help. Thanks in advance.
