Hi,

Trying to run a java program, and getting an error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/CommandLineParser

Reading up, I see I need the Apache commons-cli package. I've downloaded and unpacked this, and now have commons-cli-1.1.jar ... what do I need to do with this jar file? The docs don't give any advice on where it needs to be installed
