Hi Friend,

Try the following code:

import javax.swing.*;
import javax.swing.event.*;

public class Test {
public static void main(String[] args) {
JFrame frame = new SplitPaneFrame();
frame.show();
}
}

class SplitPaneFrame extends JFrame implements ListSelectionListener {
public SplitPaneFrame() {
setSize(500, 400);
list = new JList(texts);
list.addListSelectionListener(this);
description = new JTextArea();
JPanel panel1=new JPanel();
panel1.add(list);
JPanel panel2=new JPanel();
panel2.add(description);
JPanel panel3=new JPanel();

JSplitPane innerPane = new JSplitPane();
innerPane.setLeftComponent(panel1);
innerPane.setRightComponent(panel2);
getContentPane().add(innerPane, "Center");
}
public void valueChanged(ListSelectionEvent event) {
JList source = (JList) event.getSource();
Display value = (Display) source.getSelectedValue();
description.setText(value.getDescription());
}

private JList list;

private JTextArea description;

private Display[] texts = { new Display("Environment", "\n * JBOSS Server \n * IBM MQ 6.0 version \n * JDK1.4 or above\n\n"

}

class Display {
public Display(String n, String t) {
name = n;
des = t;
}

public String toString() {
return name;
}

public String getDescription() {
return des;
}

private String name;

private String des;
}

Thanks
