Error of "invalid flavor".

Question

Hi,
I am trying to print a SimpleDoc through the DocPrintJob. I am getting the error as "sun.print.PrintJobFlavorException: invalid flavor"
Where am I going wrong?
The code is as follows.
import java.awt.*;
import java.awt.print.*;
import javax.swing.JPanel;
import javax.swing.JTable;
import javax.print.*;
import javax.print.event.*;
import javax.print.attribute.*;
import javax.print.attribute.standard.*;
class DocPrint
     public static void main(String[] args)
          String testString = new String("Hi");
          SimpleDoc sd = new SimpleDoc(testString.getBytes(), new DocFlavor.BYTE_ARRAY("text/plain"), null);
          PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
          aset.add(new MediaPrintableArea(0f, 0f, 8f, 11f, MediaPrintableArea.INCH));
          PrintService pservice = PrintServiceLookup.lookupDefaultPrintService();
          System.out.println(pservice.getName());
          DocPrintJob pj = pservice.createPrintJob();
          pj.addPrintJobListener(
               new PrintJobAdapter()
                    public void printJobRequiresAttention(PrintJobEvent pje)
                         System.out.println(pje.getPrintEventType());
          System.out.println("After creating the Doc Print Job " + pj.getPrintService().getName());
          try
               pj.print(sd, aset);
          catch(Exception e)
               System.out.println(e);
}

The same error is thrown for any flavor too like DocFlavor.STRING.
Why is it so?
Thanks in advance.
