I can see the applet loaded and all swing elements in browser when i try to click print it just wont do anything. In eclipse run it works fine.
I know this is security issue so i have also added policy (C:\Program Files\Java\jre7\lib\security\java.policy file)
grant codeBase "http://localhost:8080/appletproj/*" {
permission java.security.AllPermission;
};

But even this does not help. please guide me where am I going wrong.
SOLUTION
Frankly i did not got solution to work, rather it was not a security issue so creating new question with actual error
So to get the exact error i enabled java console (suggested by andrew), you can go here for how to do it.
UPDATE
After few days I got it working, the issue was jna.jar and platform.jar which were already signed so whenever i signed them using jarsigner it never worked and i never got any error (so i never looked at them), when i verified it using jarsigner i figured it out. Then i unsigned them and signed it using same key which i used with my jar (Hope it will help others)
..also added policy .. But even this does not help.
Policy files are rarely, if ever, a good idea. If the code needs to be trusted, digitally sign the archive(s).

The problem is not in the ActionListener, the problem is in the ListSelectionListener; when you delete the row, the row that you're deleting no longer exists; if you want to change the selected row, you have to use the new selected row from the event; probably by using getFirstIndex().
You also need to ensure that the row exists, so that when you delete a row, there's still a valid value to select.
In other words, change your ListSelectionListener to this:
table.getSelectionModel().addListSelectionListener(new ListSelectionListener(){
public void valueChanged(ListSelectionEvent e){
int firstIndex = e.getFirstIndex();
if(firstIndex >= 0 && firstIndex < model.getRowCount()) {
del.setEnabled(true);
numeField.setText(model.getValueAt(firstIndex, 1).toString());
} else {
del.setEnabled(false);
}
}
});
I'm trying to make my program load a txt file with JFileChooser, but it doesn't seem to work. When I press the JButton, the console gives me a lot of errors. Here's the entire code so far:
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import javax.swing.*;
import javax.swing.JFileChooser;
public class Sudoku extends JFrame{
JPanel mainWindow = new JPanel();
JPanel buttonWindow = new JPanel();
JPanel sudokuArea = new JPanel();
JButton load = new JButton("Load");
JButton solve = new JButton("Solve");
JTextArea sudokuGrid = new JTextArea();
Field field = new Field();
public static void main(String[] args) {
new Sudoku();
}
public Sudoku(){
super("SudokuSolver");
setSize(200,300);
setResizable(false);
setDefaultCloseOperation(EXIT_ON_CLOSE);
add(mainWindow);
mainWindow.setLayout(new BorderLayout());
mainWindow.add(buttonWindow, BorderLayout.SOUTH);
mainWindow.add(sudokuArea, BorderLayout.CENTER);
buttonWindow.add(load);
buttonWindow.add(solve);
sudokuArea.setLayout(new BorderLayout());
sudokuArea.add(sudokuGrid, BorderLayout.CENTER);
sudokuGrid.setFont(new Font(Font.MONOSPACED, Font.PLAIN, 12));
sudokuGrid.setEditable(false);
sudokuGrid.append(field.toString());
load.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
loader();
}
public void loader(){
JFileChooser sumtin = new JFileChooser();
if(sumtin.showOpenDialog() == JFileChooser.APPROVE_OPTION)
{
File filer = sumtin.getSelectedFile();
field.fromFile(filer.getName());
sudokuGrid.setText(field.toString());
mainWindow.revalidate();
mainWindow.repaint();
}
}
} );
setVisible(true);
}
The field method is from another class called Field, but it's not really relevant (I think).
Here's what the console says:

I'm not really sure what to make of it, as I don't really know what it means. Any pointers?
EDIT: New errorcode after trying David Colers code:
Sudoku.java:49: error: method showOpenDialog in class JFileChooser cannot be app
lied to given types;
if(sumtin.showOpenDialog() == JFileChooser.APPRO
VE_OPTION)
^
required: Component
found: no arguments
reason: actual and formal argument lists differ in length
1 error
you are not handling the JFileChooser correctly for one thing.
EDIT: changed this keyword to null.
JFileChooser sumtin = new JFileChooser();
if(sumtin.showOpenDialog(null) == JFileChooser.APPROVE_OPTION)
{
File filer = sumtin.getSelectedFile();
field.fromFile(filer.getName());
sudokuGrid.setText(field.toString());
mainWindow.revalidate();
mainWindow.repaint();
}
you missed a few steps:
first create a filechooser
JFileChooser fileChooser = new JFileChooser();
show it, and get the result
int result = fileChooser.showOpenDialog(this);
And if the user has opened a file, you can get it and do what you want
if (result == JFileChooser.APPROVE_OPTION) {
File file = fileChooser.getSelectedFile();

}

Overall it's better to use latest version 5prealpha and the API described at http://cmusphinx.sourceforge.net/wiki/tutorialsphinx4
As for your exception, it says that class is not found. You need to pack that class into jar in order to run your code. There could be also a difference in package name. Recently edu.cmu.sphinx.jsapi package was renamed to edu.cmu.sphinx.jsgf. You might have issues to update that.
today I'm having a bit of a slight, see, I'm trying to run my code and I'm getting a NullPointerException. The clues in the exception leads me to this function right here:
private void irGuiJuego(JFrame frame){
SwingConsole.run(new GUIJuego(), 800, 600, true);
frame.dispose();
}
Where SwingConsole would have this code:
package utiles;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;
public class SwingConsole {
public static void run(final JFrame frame, final int width, final int height, final boolean exitOnClose) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
if (exitOnClose)
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(width, height);
//frame.setResizable(false);
frame.setVisible(true);
}
});
}
public static void run(final JFrame frame, final int width, final int height, final boolean exitOnClose, final String title) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
if (exitOnClose)
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setTitle(title);
frame.setSize(width, height);
frame.setVisible(true);
}
});
}
}
It is kind of odd, considering that I'm using the same method to open up another frame, in this function to be specific:
private void volverMenuInicio(JFrame frame){
SwingConsole.run(new MenuInicio(), 300, 150, true);
frame.dispose();
}
I'll leave you guys a pastebin of the GUIJuego Frame, since it's sort of excessive to post it here: http://pastebin.com/LSXbc7KE , have the pastebin of the other frame too, in case you need it: http://pastebin.com/hbdd7j84
Edit: Here's the stacktrace, sorry for the lack of it before!

Thanks for reading, by the way!
The NPE is being thrown from line 113 in GUIJuego.java, as the stack trace indicates:
panelDatosCiudad.add(arcaLabel);
It's happening because arcaLabel, defined in line 35, is never set to a value, and so you're adding a null JLabel to the container.
Update: If I move the code to be within the mouseclick event (i.e. instead of calling initMarksScreen() I just put the code directly in) it works as expected. So my problem is calling the code in its own method. Does this mean if I want to perform the same steps at another point or on a different button that I have to have the code directly in there instead of in a method I can call?
I am fairly new to Java and trying to create a button that adds a JScrollPane which contains a JTable.
It is called by:
public void mouseClicked(java.awt.event.MouseEvent evt) {
initMarksScreen();
}
The code is:
public final void initMarksScreen() {
String[] columnNames = {"Student ID",
"Last Name",
"Firstname",
"Status",
"Degree",
"Candidate No.",
"Stage",
"Year",
"Code",
"Title",
"Grade Mode",
"Mark",
"Result"};
Object[][] data = {
{"100123456", "Cooper","Sheldon", "Signed Up", "BSc Physics","1201234","1","12","PH1001","Blackholes and Revelations","D",new Integer(99),"P"},
{"100123456", "Cooper","Sheldon", "Signed Up", "BSc Physics","1201234","1","12","PH1025","Astrophysics","D",new Integer(95),"P"}
};
JTable tMarks = new JTable(data, columnNames);
JScrollPane scrollPane = new JScrollPane(tMarks);
tMarks.setFillsViewportHeight(true);
panelCentral.add(scrollPane); --!!ERROR AT THIS LINE!!
panelCentral.revalidate();
}
The panel is declared as:
private static final Container panelCentral = null;
As I'm quite new to Java I imagine there is an easy fix but if I need to add an SSCCE.
Everything displays fine until I click the button then the error I get is:

if panelCentral is JPanel and its not initialized, initialize before add
panelCentral = new JPanel();
panelCentral.add(scrollPane);
