Hi, The trick is to get contrib on the class path of java so it can find the content of the library. The class path defines were Java will search for the components (classes in Java) to load while running. Clojure code is compiled on the fly and ends up as a being loaded as a Java class and may be present in libraries either as .clj files or as pre-compiled Java classes (.class files).
So: java -cp clojure.jar:clojure-contrib.jar -server clojure.main clojure.main being the main program called (in this case it starts a REPL) and -cp (ClassPath) being the list of librairies you want to use. The libraries are colon delimited and I think it's the same on both Windows and u*x. -server is used for performance reasons. It modifies the behavior of the Java virtual machine and makes it run faster for our purpose. This should get you started.
