JList & JDBC display problem. Help, and Thanks.

Question

I wrote the three parts of Code, want to display the a column of database.
import java.awt.*;
public class Application1
     private boolean packFrame=false;
     static
          try
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               System.out.println("Success loading MySQL Dvier...");
          catch (Exception e)
               System.out.println("Error loading ...");
               e.printStackTrace();
     public Application1()
          Frame1 frame = new Frame1();
        frame.pack();
        frame.validate();
          frame.setVisible(true);
     public static void main(String []args)
          new Application1();
}second is :
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.sql.*;
public class Frame1 extends JFrame
     private JPanel contentPane;
     private JScrollPane jScrollPane1=new JScrollPane();
     private JList jList1=new JList();
     private Connection con = null;
      Statement stmt1 = null;
     private ResultSetListModel resultSetListModel1=new ResultSetListModel();
     static
          try
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               System.out.println("success loading JDBC-ODBC Bridge Driver...");
          catch(Exception ce)
               System.out.println("Error loading JDBC-ODBC Bridge Driver...");
               ce.printStackTrace();
     public Frame1()
          enableEvents(AWTEvent.WINDOW_EVENT_MASK);
          try
               jbInit();
               dataInit1();
          catch(Exception e)
               e.printStackTrace();
     private void jbInit() throws Exception
               setTitle( "TEST JList" );
              setSize(1000,800);
            getContentPane().setLayout(new BorderLayout());
            JPanel topPanel = new JPanel();
              topPanel.setLayout( new BorderLayout() );
              getContentPane().add( topPanel );
     private void dataInit1() throws Exception
          try
               con=DriverManager.getConnection("jdbc:odbc:playerInfor","root","");
               System.out.println("Success eastablisheing the connection...");
               stmt1=con.createStatement();
               ResultSet rs1=stmt1.executeQuery("select pace from physical;");
               resultSetListModel1.setResultSet(rs1,"pace");
               jList1.setModel((ListModel)resultSetListModel1);
               con.close();
               System.out.println("Connection is closed");
          catch(Exception ex)
               throw ex;
}last one is:
import javax.swing.*;
import java.sql.*;
import java.util.Vector;
public class ResultSetListModel extends AbstractListModel
      Vector data = new Vector();
     public ResultSetListModel()
          data.removeAllElements();
          data.addElement(new String(""));
     public void setResultSet(ResultSet resultset, String coumnname) throws SQLException
          data.removeAllElements();
          try
               while(resultset.next())
                    data.addElement(new String(resultset.getString(coumnname)));
          catch (SQLException ex)
               throw ex;
          finally
               if(data.size()==0)
                    data.addElement(new String(""));
     public int getSize()
          return data.size();
     public Object getElementAt(int index)
          return data.elementAt(index);
}when i try to run application1.java, it is not working.

Hi,
What do you mean by "it's not working"? Do you get any error messages you suppose us to guess? Or does it refuse to compile?
You have to be more specific.
