[Retep-PDF] (no subject)

[Howard, J. <Jef...@wi...>]

Hi,

I've been attempting to use retep-pdf (v2.4.1) as a print service under =
Java 1.4.2 and I've run into a bit of a problem.
For what I'm doing with this program I need to be able to represent a =
hierarchy of objects (using a JTree in the GUI).  I've extended the =
JTree to make it printable and it prints beautifully to a real printer =
so I'm confident that my code is correct.=20
Things turn sour very quickly as soon as I try to use retep-pdf to =
generate a PDF of the report.  I get a NullPointerException from =
retep-pdf.  I've included the stack trace below.
This may or may not be relevant, but the JTree I'm using is rather =
heavily modified so that the leaves of the tree are actually JPanels =
containing a number of other SWING components (JLabels, Icons, progress =
bars, and a dynamic spacer) instead of the simple JLabels used by =
default in the JTree.

Here's the code snippet that launches the print action:
            PrintRequestAttributeSet pras =3D new =
HashPrintRequestAttributeSet();
            DocFlavor flavor =3D DocFlavor.SERVICE_FORMATTED.PRINTABLE;
            PrintService[] ps =3D =
PrintServiceLookup.lookupPrintServices(flavor, pras);
            PrintService dps =3D =
PrintServiceLookup.lookupDefaultPrintService();
            PrintService svc =3D ServiceUI.printDialog(null, 200, 200, =
ps, dps, flavor, pras);
            if (svc!=3D null){
                DocPrintJob job =3D svc.createPrintJob();
                DocAttributeSet das =3D new HashDocAttributeSet();
                Doc doc =3D new SimpleDoc(this,flavor,das);
               =20
                try{
                    job.print(doc,pras);
                }catch (PrintException pe){
                    System.out.println("Exception while printing: =
"+pe.getMessage());
                    pe.printStackTrace();
                }
            }


Any help would be greatly appreciated  :-)

Thanks!
