How to read/write data in Notepad?

Question

Hi to all,
Im creating a simple application to write data in notepad using wireless toolkit 2.5. For that i have created a notepad file(raj.txt) manually and saved in the location "D:\WTK25\appdb\DefaultColorPhone\filesystem\root1\raja.txt". When i run in the emulator..Its shows the following exception " java.io.IOException : Root is not accessible". I got struck in this thing. For your convenience i have attached my source code also. Please correct and explain me
1. Where should i store the notepad file in Wireless Toolkit 2.5?
2. If i use wireless toolkit 2.5, What is the link should i give in the method Connector.open("file:///???")?
My source code:
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import java.io.*;
import javax.microedition.io.*;
public class FileConnection extends MIDlet implements CommandListener
private Display display;
private Form form;
Thread s=new Thread();
public FileConnection ()
display = Display.getDisplay(this);
form = new Form("Write To File");
form.setCommandListener(this);
public void startApp() throws MIDletStateChangeException
try
OutputConnection connection = (OutputConnection)
Connector.open("file://localhost/D:/WTK25/appdb/DefaultColorPhone/filesystem/root1/raj.txt", Connector.WRITE );
OutputStream out = connection.openOutputStream();
PrintStream output = new PrintStream( out );
output.println( "This is a test." );
out.close();
connection.close();
Alert alert = new Alert("Completed", "Data Written", null, null);
alert.setTimeout(Alert.FOREVER);
alert.setType(AlertType.ERROR);
display.setCurrent(alert);
catch( ConnectionNotFoundException error )
Alert alert = new Alert("Error", "Cannot access file.", null, null);
alert.setTimeout(Alert.FOREVER);
alert.setType(AlertType.ERROR);
display.setCurrent(alert);
catch( IOException error )
Alert alert = new Alert("Error", error.toString(), null, null);
alert.setTimeout(Alert.FOREVER);
alert.setType(AlertType.ERROR);
display.setCurrent(alert);
public void pauseApp() {}
public void destroyApp(boolean unconditional) {}
public void commandAction(Command command, Displayable displayable) {}
}
