hi friends.please help

  To: comp.lang.java.gui
I am trying t make a jTable Using Abstract TableModel. But my JTable
doesnot appear on the frame.I have written two classes myTable and
jTable2 .My code is given below:

import javax.swing.*;
import java.awt.*;

public class myTable {
    public static void main(String args[]){
        JTable2 tbl2=new JTable2();
        JTable aTbl=new JTable(tbl2);
        aTbl.updateUI();
        aTbl.setVisible(true);
        JFrame frame=new JFrame("Jtable using AbstractTableModel");
        JPanel pan=new JPanel();
        JScrollPane scp=new JScrollPane();
        scp.add(aTbl);
        pan.add(scp);
        frame.getContentPane().add(pan);
        frame.setVisible(true);
        frame.pack();
    }

}

import javax.swing.*;
import java.sql.*;
import java.util.*;
import javax.swing.table.*;

public class JTable2 extends AbstractTableModel{
    Connection con;
    Statement stmt;
    ResultSet rs;
    int columns;
    Vector allRows;
    Vector row=new Vector();
    String [] columnNames={"ID_CODE","NAME","SECTION"};

    public JTable2(){
        // connect to database
        try{
        db_connect();
        getData();
        }catch(Exception ex){
            ex.printStackTrace();
        }

    }
    void db_connect() throws SQLException{
        try{
            Class.forName("oracle.jdbc.driver.OracleDriver");

con=DriverManager.getConnection("jdbc:oracle:thin:@158.144.71.242:1521:dbadp","payroll","sush");
            System.out.println("Connected");
        }catch(Exception ex){
            ex.printStackTrace();
        }
    }
    void getData() throws SQLException {
        try{
            stmt=con.createStatement();
            rs=stmt.executeQuery("select idcode,id_name,sec_code from
employee");
            ResultSetMetaData rsMetaData=rs.getMetaData();
            columns=rsMetaData.getColumnCount();
            allRows=new Vector();
            while(rs.next()){
                Vector newRow=new Vector();
                for(int i=1;i<=columns;i++){
                    newRow.addElement(rs.getObject(i));
                    }
                allRows.addElement(newRow);
                    }

        }catch (Exception ex){
            ex.printStackTrace();
        }
    }
    public int getRowCount(){
        return allRows.size();
    }
    public int getColumnCount(){
        return columns;
    }
    public Object getValueAt(int aRow,int aColumn){
        row=(Vector) allRows.elementAt(aRow);
        return row.elementAt(aColumn);
    }
      public boolean isCellEditable(int row, int col){
            return false;
          }
