ADF Faces & BC 10.1.3.4: Barcode Printing & ADF version of WebUtil?

Question

Hi all,
Our existing application is built with Oracle Forms/Reports 9i which also uses Oracle WebUtil 10g because we need to print bar code labels. Our oracle forms appilcation invokes "Host" commands which allows it to print directly to the server's printer ports, this is accomplished by invoking WebUtil functionality which somehow bypasses(probably not the correct term to use) the jvm security sandbox. We need to have a similar barcode printing functionality on our ADF Faces/BC application however I'm not aware of the existence of "ADF WebUtil" which can be configured to allow access to printer ports.
Here is some code snipets for the 9i Forms application for printing (which is done through Internet Explore Browser)
CLIENT_TEXT_IO.PUT_LINE(myPrinter, output_str);
If lineType = 'B' Then vertStartTemp := vertStartTemp + vertBStep;
Else vertStartTemp := vertStartTemp + vertAStep;
End If;
End Loop;
/* last line */
output_str := 'P1'||chr(13)||chr(10);
CLIENT_TEXT_IO.PUT_LINE(myPrinter, output_str);
CLIENT_TEXT_IO.FCLOSE(myPrinter);
EXCEPTION
WHEN OTHERS THEN
CLIENT_TEXT_IO.FCLOSE(myPrinter);
message(sqlerrm );
Raise Form_Trigger_Failure;
END;
Here is some java code which uses the awt library (only works locally due to jvm secuirty sandbox)
public void testZebraBarCode(ActionEvent actionEvent) {
//called from a commandButton action listner. will fail upon deployment to server because its trying to access native resouces.
try {
PrintService psZebra = null;
PrinterJob printJob = PrinterJob.getPrinterJob();
if (printJob.printDialog()) {
psZebra = printJob.getPrintService();
DocPrintJob job = psZebra.createPrintJob();
String s =
// Set Reference Point
// Clear Image Buffer
// Print direction (from Bottom of buffer)
// Set label Length and gap
"R0,0\n" + "N\n" + "ZB\n" + "Q122,16\n" +
"A160,2,0,3,1,1,N,\"DATA: CARUGATE\"\n" +
"B160,30,0,1A,2,7,50,N,\"612041600021580109\"\n" +
"A160,92,0,1,1,1,N,\"AIA AGRICOLA IT.ALIMENT.S - 594679/VR\"\n" +
"P1\n";
byte[] by = s.getBytes();
DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
// MIME type = "application/octet-stream",
// print data representation class name = "[B" (byte array).
            Doc doc = new SimpleDoc(by, flavor, null);
            job.print(doc, null);
        } catch (PrintException e) {
e.printStackTrace();
Can anyone point me to the proper direction on how to accomplish this task?
Thanks,
Wes

Hi,
if you build a web application then you have to integrate a Swing based Applet to the web age to access the local client. You can't with native web means
