Adding scrollpane on TextArea

I am making a GUI in which i am adding the horizontal scroll bar in to TextArea because the length of the label/line that will be display in the TextArea is more than the width of the TextArea.

This is my code where I create the pane. But nothing seems to happen....

//create the text area for description and add into the main frame 

public static JTextArea textArea = new JTextArea();
textArea.setEditable(false);                                        
textArea.setLineWrap(true);
textArea.setPreferredSize(new Dimension(100,600));

scrollpanel = new JScrollPane(textArea);    
scrollpanel.setBounds(20, 600, 920, 130);
scrollpanel.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);  
scrollpanel.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
scrollpanel.setBorder(BorderFactory.createTitledBorder("Description"));
frmToolToMigrate.getContentPane().add(scrollpanel);

Instead of setBounds(), override the scroll pane's getPreferredSize(), as shown here. By default, the scroll bars will appear automatically as required. Also consider implementing the Scrollable interface.

Have you looked at

http://docs.oracle.com/javase/tutorial/uiswing/components/scrollpane.html

You can also make textArea as a new class that extends TextArea java class and then implement scrollable.

public class MyTextArea extends JTextArea implements Scrollable{

//Whatever you want to do

}
