JPS java service print

Question

Hello everyone, I try to know how api Java Print Service work thus .I try to compile their example on
http://access1.sun.com/tools/JPSDemo/jpsdemo.html
and to compile their application on
http://access1.sun.com/tools/JPSDemo/jpsdemoapp.zip
Here is my problem when I carry out the print application, on
the Method
public PrintService[] getPrintServices() {
//Before sending the request for lookup, list the Attribute set here
Attribute[] nattr = aset.toArray();
int loop = nattr.length;
System.out.println("New Attributes set:");
for (int i = 0; i < nattr.length; i++) {
System.out.println("test " + nattr);
System.out.println(newl);
for(int i = 0; i <= loop; i++ ) {
nattr = aset.toArray();
for (int k = 0; k < nattr.length; k++) {
System.out.println("attribute " + nattr[k]);
services = PrintServiceLookup.lookupPrintServices(myFlavor, aset);
service = PrintServiceLookup.lookupDefaultPrintService();
if (services.length > 0) {
break;
else {
System.out.println(
" No Print Services found, will compromise attribute");
compromiseAttribute(i); //remove one attribute
for (int ck = 0; ck < compromised.length; ck++ ) {
if (compromised[ck] != null ) {
System.out.println(compromised[ck]);
// Get the supported PrintServiceatribute categories that we can specify
for (int j = 0; j < services.length; j++) {
Class[] psattribute = services[j].getSupportedAttributeCategories();
System.out.println("Printer name is: " + services[j].getName());
System.out.println(" ");
//System.out.println("No. of Print Service attribute categories are " + psattribute.length);
System.out.println("Supported Print Service attribute categories are: ");
for (int i = 0; i < psattribute.length; i++) {
System.out.println(psattribute[i]);
System.out.print(" ");
Object value = services[j].getSupportedAttributeValues(psattribute[i], null, null);
if (value == null) {
break;
if (value.getClass().isArray()) {
Object[] v = (Object[]) value;
for (int k = 0; k < v.length; k++) {
if (k > 0) {
System.out.print(", ");
System.out.print(v[k]);
else {
System.out.print(value);
System.out.println();
return services;
It return me that there is no service available without tell mewhich attribute doesn t work . Then why, there is not no service
available or what is not available to circumvent the problem
thank you has all.

I think that if someone has ever found an interesting way to print pdf files from java, especially if this uses the 1.4 JPS API, It would be nice to put it on this forum and not share it via e-mail with some happy-fews (just my 2 cents).
I have been looking at this for a while and could not find any decent solution (spawning an Acrobat Reader with the /t option does not allow to control enough printer options like 2-sided, n-up, paper trays, ...).
I think of a solution that would convert the pdf to a plain ps document and stream it with JPS to the printer. I am trying to integrate Ghostscript with my app using JNI to do so. Has anyone used this or another solution to get a PS file out of a pdf document within java?
Did anybody find or write a java pdf renderer that could be used to implement the Pageable and Printable interfaces?
Please let me (and us all) know...
