Since this is a servlet, I presume it is running on a server. It is very
likely that X11 is not running on the server. Even if it is, any decently
configured HTTP server will not execute servlets as a regular user, but
some special user like nobody. In that case, even if the AWT system
knew the right display (:0.0) it would not be allowed to connect to it.
It does seem like Sun made a design error if you need to initialize AWT
in order to read an image's hight and width. You might be tempted to use
xhost to allow all users access to the local X11 console, but I would not
recommend that ! Other alternatives include using JNI or invoking a
program that will print the size of the image (very inefficient, but I
I guess you could cache the results). You could also look for third
party native libraries that allow you to access meta-info about popular
image type (gif, pgn, jpg, ...)
