I have a jar file that contains some Java classes. How do I tell scala to look in this jar file?

As with Java, you can set a -classpath argument:

/tmp> scala -classpath <jarfile>

Alternatively you can set the CLASSPATH environment variable to point to the jar file.

I am having troubles using fsc, the Fast Scala Compiler, on Macintosh OS X

The Fast Scala Compiler maintains some code resident in memory and uses a network connection in order to communicate with it; the OSX firewall might interfere with this communication. In order to configure the firewall accordingly, please follow this guide.
