No (you can, but I would never do it)

If more users on your system should be able to run the programm I would 
put it in /usr/local/bin or maybe /usr/local/java. If only one user 
should be able to run it, you could also put it in /home/[user]/bin/, or 
if you prefer that /home/[user]/java or even /home/[user]/bin/java/

cd (or don't I understand your question?)

Anyway, the script might contain:

cd [path to the programm]
java -jar ./Arachnophilia.jar

This script must be executable (chmod +x) and in the $PATH of the users 
who should be able to run it. And remember: the current directory on 
standard Ubuntu systems is not in your path. That is the reason for 
the ./ before Arac[etc]

No thanks, hope it is clear
