If you have parameters in your report then the report tries to get them 
from the user unless you either (a) give it a parameter XML file to 
read or (b) set the parameters yourself and override askForParameters() 
as described in the documentation.

Since you haven't called Report.setParameterXML Input() then the report 
is trying to ask the user. That's why it's trying to create a window, 
which is why the Java runtime is trying to use X11 and the DISPLAY 
environment variable.
