Problems with Jtable connected to data base

[elizabeth]

I'm new in java and I have a problem with a Jtable.
I'm doing a windows that has a Jtable in a JScrollPane, it should shows information from data base, but it doesn't

this is the code

public

class Students extends JDialog { 

private static final long serialVersionUID = 1L; 

private JPanel jContentPane = null; 

private JButton jButton1 = null; 

private JScrollPane jScrollPane = null; 

private JTable jTable = null; 


/** 

* @param owner 

*/ 

public Students () { 

super(); 
initialize();

}


private void initialize() { 

this.setSize(486, 230); 

this.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE); 


this.setContentPane(getJContentPane()); 

this.setLocationRelativeTo(null); 
}




private JPanel getJContentPane() { 

if (jContentPane == null) { 

jContentPane = new JPanel(); 

jContentPane.setLayout(null); 

jContentPane.add(getJButton1(), null); 

jContentPane.add(getJScrollPane(), null); 
}


return jContentPane; 
}



private JButton getJButton1() { 

if (jButton1 == null) { 

jButton1 = new JButton(); 

jButton1.setBounds(new Rectangle(174, 168, 100, 25)); 

jButton1.setText("Exit"); 

jButton1.addActionListener(new java.awt.event.ActionListener() { 

public void actionPerformed(java.awt.event.ActionEvent e) { 
Students .

this.dispose(); 
}

});

}


return jButton1; 
}


private JScrollPane getJScrollPane() { 

if (jScrollPane == null) { 

jScrollPane = new JScrollPane(); 

jScrollPane.setBounds(new Rectangle(15, 16, 453, 131)); 

jScrollPane.setViewportView(getJTable()); 
}


return jScrollPane; 
}




private JTable getJTable() { 

if (jTable == null) { 

//jTable = new JTable(); 
DefaultTableModel model = 

new DefaultTableModel(); 
JTable jTable = 

new JTable(model); 

modelo.addColumn(

"Name"); 
model.addColumn(

"Number"); 

ResultSet rs;


try { 
rs = Connection.

st.executeQuery("SELECT name,nro FROM student order by name,nro"); 

while (rs.next()) 
{



Object [] row = 

new Object[2]; 



for (int i=0;i<2;i++) 
row [i] = rs.getObject(i+1); 



model.addRow(row ); 

}

} 

catch (SQLException ex) { 
JOptionPane.showMessageDialog(

null, "Error  "+ex, null, JOptionPane.ERROR_MESSAGE); 
}

}


return jTable; 
}

}

Which exception do you get? We can't test this code on our side since we don't have your database. We can only help you to track the error if any.

write this:

this.getContentPane().add(getJContentPane() );

instead of:

this.setContentPane(getJContentPane());
