Problem |
When developing on Windows®, and deploying to WebSphere
Application Server on a Unix Operating System, you could encounter
problems generating an image dynamically in a WebSphere Application
Server. |
|
Solution |
-Djava.awt.headless=true as a parameter on the WebSphere
Application Server JVM™
OR
- Invoke VirtualFrameBuffer(Xvfb) on Unix Server
After X11 is installed, the system must be restarted
Ensure -vfb is specified when starting X11 (most likely when booting the
machine).
For instance, the following command may be used:
/usr/bin/X11/X -force -vfb -x GLX -x abx -x dbe
Add the following lines to /WebSphere/AppServer/bin/startupServer.sh :
# Setting of the DISPLAY variable
# is required for the Ad Builder
# system to connect to the X11
# server through the Xvfb (Virtual Frame Buffer=)
DISPLAY=3D127.0.0.1:0.0
export DISPLAY
NOTE:
VirtualFrameBuffer(Xvfb)
is an X server that can run on systems with no display hardware and no
physical input devices. It emulates a dumb terminal framebuffer using
virtual memory and is limited in the number of colors and fonts it can
handle. |
