Hi Daniel,
that should be enough.. you're probably still missing some library or
you're not correctly passing the define to the jvm when you
launch your servlet container (tomcat?). Check your logs!
The final command that actually executes the jvm should be
something like:
# java -Djava.awt.headless=true -cp<yourClasspath> <MainClass> [opts]
see the position of the define.. order is important!
Hope that helps.
Check your logs and make sure

Hi Robi,
Thanks for the help.
I now installed Xlib, I am using -Djava.awt.headless=true, and still
have this frustrating message :
"Gtk-WARNING **: cannot open display:"
Does somebody know anything else I should configure to get it run ?
What could I do to find out what is missing ?

Hello,
I just installed the binary version of Fop-0.94 on a server running
under Fedora Core 5.
I have Java version 1.4.2, and trying to have have fop running.
Generating fo output works fine.
Trying to generate pdf output results in "Gtk-WARNING **: cannot open
display:"
Looks like some library uses Gimp toolkit, which needs Xlib. I do not
have Xlib installed.
I tried setting -Djava.awt.headless=true but without any effect.
I looked at several places and found this problem mentioned but not
really solved.
So my questions are :
* just to know : which is the library using Gtk ?
* do I need to install Xlib or is there another solution ?
Yes. You need to install Xlib
* do I need an X server running ?
No. just use -Djava.awt.headless=true
Or in short : has anybody *solved* this problem, and how ?
Yes. It is very common to run a server in headless mode (i.e. w/o X)
Thank you for your help.
Daniel
