another lame hack (ALH) #tags java,oneliners,shell So I got bored and after discovering that java doesn't let you (Or to my knowledge) access enviroment variables.
ENVS=`env | sed -e 's/"/\"/g' | sed -e 's/^(.*)=(.*)$/-D1="2"/' | \
sed -e 's,.$,& \\,' && echo "$*"`
sh -c "java ${ENVS}"
Put that in a shell script and call it with the same parameters you'd normally call java with. ie;./lamehack.sh testSystem.getProperty(). For example, you could now do: System.getProperty("DISPLAY") to grab the DISPLAY enviroment variable.
