I believe the default setting for the JScrollPane is for the scroll bars to
only to be shown as needed. You have not added anything to the JScrollPane,
so they will not show up. You can set explicitly with:

jScrollPane1.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAY
S);

Hope that is helpful.

Following is a very short testing code. There is no scrollbar with
JScrollPane ! Same thing with ScrollPane. Help is wanted and
aprreciated!

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

public class myFrame extends JFrame {
 JScrollPane scrollPane;
 myCanvas c;
 public myFrame(){
  c = new myCanvas();
  scrollPane = new JScrollPane(c);
  this.getContentPane().add(scrollPane);
 }

 public static void main(String args[]){
  myFrame f = new myFrame();
  f.setSize(200, 300);
  f.setVisible(true);
 }
}

class myCanvas extends Canvas{
 Image img;

 public myCanvas(){
  file://you may change image to your own
  img = Toolkit.getDefaultToolkit().getImage("AboutSwing.gif");
 }

 public void paint(Graphics g){
  g.drawImage(img, 0, 0, this);
 }
}
