Hi,
I have an problem in zk's application when export data to pdf format; the message error is follow:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
The application's server is tomcat 7 and running on linux ubuntu 12.04.
Thanks from Colombia.
Hello kenshin,
This has to do when a web application that does something related to graphics and you're running it on a server that isn't running a windowing system.
You need to somehow set System.setProperty("java.awt.headless", "true");
Tell the server team to start whatever Java they are starting with an additional command line parameter:
java -Djava.awt.headless=true
You could additionaly set the following system propery if X11 is installed
DISPLAY=:0.0 export DISPLAY
Best Regards,
Darksu
