But I get this when I run it:
null argument passed

PrintServiceLookup found 0 printers
Java program completed"

I'm guessing it can't find anything. Can you verify that it finds something on your system? I called it from a submitted RPGLE program first, then tried a direct call using the JAVA cl command. Same result both times.

Can you think what might be missing in my setup given that I have a large number of printers and OUTQs setup on the iSeries.

Add /QIBM/ProdData/OS400/Java400/ext/ibmjps.jar to your class path.

Then the javax.print.* stuff should work.

Try this:

import javax.print.DocFlavor;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;

public class Printers {

* @param args
public static void main(String[] args) {
PrintService defaultPrintService;
defaultPrintService =

System.out.println("DEFAULT PRINTER:");

PrintService[] services;
services = PrintServiceLookup.lookupPrintServices(null,

System.out.println("PrintServiceLookup found " + services.length
+ " printers");

for (int i = 0; i < services.length; i++) {
PrintService service = services[i];
System.out.println("PRINTER " + i);

private static void describe(PrintService printService) {
if (printService == null) {
System.out.println("null argument passed");

System.out.println("Name: " + printService.getName());
DocFlavor[] flavors = printService.getSupportedDocFlavors();
for (int i = 0; i < flavors.length; i++) {
DocFlavor flavor = flavors[i];
System.out.println("F " + flavor);

Class[] categories =
for (int i = 0; i < categories.length; i++) {
Class class1 = categories[i];
System.out.println("A " + class1);

Subject: Printing from Java


I am trying to print a PDF using Java called from RPGLE. I know there are all sorts of problems with PDF printing but I think I have a potential solution in using the PDFRenderer package from Sun. The problem I am currently having is that the java.awt.print.PrinterJob.getPrinterJob()
method is returning a nullpointer exception.

I'm thinking that I am going about this all wrong as AWT is not really implemented properly on the iSeries. What iSeries print options are available through java400? Can I send a spooled file to (or even use) an OUTQ at all? Or is that side of things totally disconnected when using Java?
