Yoou could try the command (in /usr/bin/)
$ java -classpath "$classpath:/usr/bin/" -jar ./Arachnophilia.jar
or (I'm not sure which will work, but I expect one of them will)
$ java -classpath $classpath:/usr/bin/Arachnophilia.jar" -jar ./
Arachnophilia.jar

(on one line of course)
With the one that works it may not be necessary to cd to /usr/bin/ first.
(You do have java-6-openjdk installed, do you? If not, it will not work.)

I would not have used /usr/bin/ anyway because that is where your 
distribution puts its executables and may remove them. /usr/local/ is the 
usual place for things the administrator of the machine installs and 
should not be touched by the distribution.
