With this code:


   Toolkit tk = Toolkit.getDefaultToolkit();
   JobAttributes  ja = new JobAttributes(); // getDialog == JobAttributes.DialogType.NONE
   PageAttributes pa = new PageAttributes();

   ja.setDestination(JobAttributes.DestinationType.FILE);
   ja.setFileName("jn-resolution");
   ja.setDialog(JobAttributes.DialogType.NONE);

   PrintJob pj = tk.getPrintJob(null, "finalize", ja, pa);

I get the following exception

  java.awt.HeadlessException
        at sun.awt.motif.PSPrinterJob.printDialog(PSPrinterJob.java:507)

According to the javadoc, setting DialogType.NONE will avoid the throwing of HeadlessException.

See attached .tar file for the full test case.

============================

the headless spec has been updated to indicate that PrintJob is not
supported in that mode

EVALUATION Closing this out as a duplicate of 4285177. michael.martak@Eng 2000-10-03 Reopened, and reassigning to 2D. michael.martak@Eng 2000-10-04 =========== There' no intention of supporting Toolkit.getPrintJob in headless mode in the merlin release. The headless spec should not be saying this would work and it needs to be amended on Toolkit.getPrintJob to say that an exception is always thrown in headless mode. phil.race@eng 2000-11-08 ========================
