Setting Up

Probably a path issue...

http://chibimagic.wordpress.com/2011/07/28/selenium-server-2-0-on-mac-os-xwindows-with-custom-firefox-path/

I usually run something like

strace -f -o /tmp/log.strace java -jar selenium-server-standalone-2.5.0.jar

grep -i stat /tmp/log.strace

to track down file / path problems...
