Java 3D problem - No X11 DISPLAY variable was set

I have following exception during Java3D application startup:

No X11 DISPLAY variable was set, but this program performed an operation which requires it.
java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
       at sun.java2d.HeadlessGraphicsEnvironment.getDefaultScreenDevice(HeadlessGraphicsEnvironment.java:77)

Problem is quite easy understand and resolve. Java 3D drive don't know address of X11 windows server. X11 server address should be stored in environment variable "DISPLAY". Environment could be set up like this:

export DISPLAY=:0.0

This will work just in case that your X11 server is at localhost. How to find X11 server address is nicely described at http://stackoverflow.com/questions/784404/how-can-i-specify-a-display
