Getting a strange exception from Tomcat

Im using a tomcat installation to do a some JPEG manipulation. From most
machines it works fine but one customer causes this exception when the
image code is hit. Why would different client machines cause problems
running the same code with the same data? Im sure its a UFU but I don't
have a clue how to debug it. Suggestions?

org.apache.jasper.JasperException: Can't connect to X11 window server
using ':0.0' as the value of the DISPLAY variable.
