I try to run the code in a sample, and it's work fine... no problems...

My code is very long... up to 2300 lines... but it's not generated by NetBeans...
The code where I have the problem is this:import java.util.*;
import java.util.Date;
import java.text.*;
import java.io.*;
import java.awt.*;
import java.awt.event.*;
import java.sql.*;
import javax.swing.*;
import javax.swing.table.*;
import javax.swing.border.*;
import javax.swing.text.*;
