Try this. I believe this is what you were asking. If not, let me know...
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.JScrollPane.*;
class test
     public static void main(String argv[])
          consoleFrame csf = new consoleFrame();
          csf.setVisible(true);
class consoleFrame extends JFrame
     public consoleFrame()
          super("Console");
          setSize(150, 200);
          JPanel p1 = new JPanel();
          JPanel p2 = new JPanel();
          JPanel p3 = new JPanel();
          JPanel p4 = new JPanel();
          JPanel p5 = new JPanel();
          JPanel p6 = new JPanel();
          JLabel l1 = new JLabel("aaaaaaaaaaaaaaaaaaaaaaa");
          JLabel l2 = new JLabel("aaaaaaaaaaaaaaaaaaaaaaa");
          JLabel l3 = new JLabel("aaaaaaaaaaaaaaaaaaaaaaa");
          JLabel l4 = new JLabel("aaaaaaaaaaaaaaaaaaaaaaa");
          JLabel l5 = new JLabel("aaaaaaaaaaaaaaaaaaaaaaa");
          JLabel l6 = new JLabel("aaaaaaaaaaaaaaaaaaaaaaa");
          p1.add(l1);
          p2.add(l2);
          p3.add(l3);
          p4.add(l4);
          p5.add(l5);
          p6.add(l6);
          JPanel content = new JPanel();
          content.setLayout(new GridLayout(6,1));
          content.add(p1);
          content.add(p2);
          content.add(p3);
          content.add(p4);
          content.add(p5);
          content.add(p6);
          // how to modify the codes in this program to make
          // the vertical-only scrollbar?
          JScrollPane jsp = new JScrollPane();
          jsp.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
          jsp.setSize(200, 100);
          JViewport view = new JViewport();
          view.setView(content);
          jsp.setViewport(view);
          this.getContentPane().add(jsp, BorderLayout.CENTER);
          this.setSize(200, 100);
}
