Problem with PDF generation on Unix

2004-07-22 04:35

Hello everybody,

 

my PDF generation works on windows but not on

UNIX. I get the following exception:

 

---

 

java.lang.InternalError: Can't connect to X11 window server using '10.49.5.49:0.0' as the value of the DISPLAY variable.

It looks like jasperReports needs an X-Window server to work properly!

 

1) Is there any way to cut this dependency to X11?

2) If no, what to do? There's X running on the machine with the mentioned IP adress.

 

Greetings Constantin

There's a couple of things you can do.

 

If you're running Java 1.4 (I think) or above, then you can use the following command in your Java code to export to PDF without requiring an X server to be running:

 

System.setProperty("java.awt.headless", "true");

 

Alternatively, given you've got an xserver running anyways, you could try doing "xhost +" which will allow any user to connect to the xserver.

 

Cheers,

Darran
