KeyReleased Event

Question

Hi everybody,
i have a JTable and what I want to is that when the user type something in the TextField the table will show the names of the company that start with the letter that the user typed. But the problem is that each time the user type the event executes 2 times, this is the code:
private void txt_searchCompanyKeyReleased(java.awt.event.KeyEvent evt) {
TableModel model = jt_Company.getModel();
ArrayList<String[]> dataArray = new ArrayList<String[]>();
String[] data = new String[ jt_Company.getRowCount() ];
String s = txt_searchCompany.getText();
System.out.println("Cantidad de filas: " + jt_Company.getRowCount()+ "\nCantidad de col: " + jt_Company.getColumnCount());
for(int i = 0; i < jt_Company.getRowCount(); i++)
   for(int j = 0; j < model.getColumnCount(); j++)
       if(model.getValueAt(i, 1).toString().startsWith(s) == true)
         data = model.getValueAt(i, j).toString();
         dataArray.add(data);
          System.out.println(" " + data[0] + "Tamano de ArrayList: " + data.  length);
jt_Company.setModel(new Business.CompanyTable(dataArray));
}//End of the methodthe method compares very well the string and the name of the companies in each row, but as mention before the method does it 2 times that means that the string array will the double of rows.
How can I do to make the event execute only one time
Thanks a lot.......

Hi camickr, i tried what you said and It works well, but now i am traying to do another thing.
Look, i want that the textfield remove the last character when the user type one of this character: ( ' / * % ? = > < etc...)and this is the code:
class MyDocumentListener implements DocumentListener {
    /** Creates a new instance of MyDocumentListener */
    public MyDocumentListener() {
    public void insertUpdate(DocumentEvent e) {
      updateLog(e);
    public void removeUpdate(DocumentEvent e) {
      updateLog(e);
    public void changedUpdate(DocumentEvent e) {
    //Plain text components don't fire these events.
    public void updateLog(DocumentEvent e) {
       int i = e.getDocument().getLength();
       String name = " ";
       try{
            name = e.getDocument().getText(i-1, 1);
            if(restriction.restrictionSearchBy(name) == true)
               JOptionPane.showMessageDialog(null, "Hola" + name);
               txt_searchCompany.getDocument().remove(i-1, 1);
               e.getDocument().remove(i-1, 1);// I tried this and did not work also
            else{
       catch(javax.swing.text.BadLocationException b){}
}but i got this exception when i run it:
