Java $CLASSPATH in f17

[Elixir]

The $CLASSPATH variable is not set by default in f17.

What path should I give in my .bash_profile for this variable?

I have the following packages installed:

$ java -version
java version "1.7.0_03-icedtea"
OpenJDK Runtime Environment (fedora-2.2.1.fc17.8-x86_64)
OpenJDK 64-Bit Server VM (build 23.0-b21, mixed mode)

My requirement is to install a jar for global runtime access. I plan to ass it to the CLASSPATH variable.
Is there some place where we can paste the jar so that it becomes runtime available?

Whereever you like. I would put it in a shared <something>/lib folder so I could reference any stray jars I wanted from one location.
