Answer 1

Like Alex mentioned, if you start java with the -cp argument, then the CLASSPATH environment is not referenced. So, instead of

java -cp /Users/smcho/bin/jar/clojure.jar clojure.lang.Repl

use

java -cp /Users/smcho/bin/jar/clojure.jar:$CLASSPATH clojure.lang.Repl

You can examine your java classpath from within the Clojure repl:

(doseq [p (.getURLs (java.lang.ClassLoader/getSystemClassLoader))] (println (.getPath p)))

Answer 2

You didn't specify what commandline you used for the first example, but note that if you use the -cp flag, the CLASSPATH environment variable is not referenced.
