ScrollPane behave differently

[Balasubramanian Chandrasekaran]

Can any one tell me the difference in the behaviour of the ScrollPane Vs JScrollPane in the following code.

/**
 * @(#)SampleText.java
 *
 *
 * @author BALASUBRAMANIAN C
 * @version 1.00 2008/1/18
 */
import javax.swing.*;
import javax.swing.text.DefaultStyledDocument;
import javax.swing.text.SimpleAttributeSet;
import javax.swing.text.StyleConstants;
import java.awt.*;
import java.awt.event.*;
 
public class SampleText extends JFrame{
        
    static DefaultStyledDocument doc = new DefaultStyledDocument();
    static SimpleAttributeSet sat = new SimpleAttributeSet();
    static int i=0;
    
    public SampleText() {

}
    
    public static void main(String[] args) {
           
        JFrame frame = new JFrame();
        JPanel panel = new JPanel();
        JTextPane text = new JTextPane();
        text.setDocument(doc);
        JScrollPane scroll = new JScrollPane(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
        text.setEditable(false);
        panel.setLayout(new BorderLayout());
        scroll.setViewportView(text);
        panel.add(scroll);
        frame.add(panel);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setMaximumSize(new Dimension(1024,768));
        frame.setMinimumSize(new Dimension(200,300));
        frame.setTitle("Hello");
        frame.setVisible(true);
        while(i<300)
        {
        try
        {
        StyleConstants.setForeground(sat,Color.GREEN);
StyleConstants.setBackground(sat,Color.BLACK);
  doc.insertString(0,"hsfdjkhskjhfjhskdfhjshdfhsjkdhfjkshdfjkhsjkdfhjskdhfkjshd"+System.getProperty("line.separator"),sat);
        i++;
        }
        catch(Exception ee)
        {
        System.out.println ("Error Occured");
        }
        }
    }
}

I tried to use the same piece of code in JScrollPane and in the output the JTextPane which holds the DefaultStyledDocument automatically wraps the text.But instead of JScrollPane(swing) if i use ScrollPane(AWT) then the JTextPane doesn't wraps the text.

Why is this behaviour?
And also i need to achieve JScrollPane without wrapping text.For that what i have to change....
Awaiting your reply

I got answer to my query in this forum.

But, can anyone explain me why JScrollPane behave like that.
