Can't print in Tomcat 4

[Jack Li]

I have a program that prints report on server. It worked fine in Tomcat 3.2.
But, after I upgraded to Tomcat 4.0.3, it does work anymore. I found that it
stops at:
 
PageFormat pf = job.defaultPage();
 
where job is "PrinterJob job = PrinterJob.getPrinterJob();"
 
Any idea that can make printing work with Tomcat 4?
 
Many thanks
