Subject RE: X11 server at :0.0

Yup, it's a problem where the full set of required X11 libraries aren't
installed on the machine your trying to run the webapp on and you're doing
something involving graphics (e.g. drawing to a buffer and serving the image
from a servlet).

Best bet is to install the X libraries, next best would be to use the
command line switch which removes the need for the X11 libs
(-Djava.awt.headless=true )

Have any of you faced this issue while deploying an application in WAS?

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

java.lang.InternalError: Can't connect to X11 window server using ':0.0' as
the value of the DISPLAY variable. I found this document on the IBM site
which says make an entry in Server>Application Servers> <Application server>
> Java and Process management> Process definition > Custom properties

Enter 'DISPLAY' in the name field (which I did) and #port number in value
field (I entered 6000). But I still get the same error.
