Re: classpath and require
Yes, exactly it was, also at some point I was trying examples/introduction (ruby's require like statement) instead of examples.introduction which all together made me lost.

Re: classpath and require
I was wondering whether putting a dot in a directory on the classpath makes a difference. On OS X, the answer is no. Unfortunately, I don't have a windows machine, so I can't check for certain what the situation is there. Another issue: I ignored case-sensitivity in my answer above. Are windows paths ever case-sensitive? (silly question, I know, but I haven't worked with windows in a while.) Another question: If you run: java -cp "c:\clojure-contrib\clojure-contrib.jar;c:\clojure \clojure.jar;c:\projects.clj\examples" clojure.main can you then just do (require 'introduction) And do try it with quotes around the classpath. The dot in projects.clj might be like a space in that it could lead to a parsing error without quotes.

To me it looks like you have gotten the most things right. As I see you understand, you must have clojure, clojure-contrib and the source on the class path. However, how these are specified can be a bit tricky. There are basically two cases: directories and jar files. When using jar files, the jar file itself must be in the class path, not the directory which contains it. In our case, the entries would be c:\clojure\clojure.jar and c:\clojure-contrib\clojure-contrib.jar, just as you wrote. When using folders with clojure source files or ahead-of-time compiled classes, the directory that contains the folder that represents the topmost component of the namespace. For example, in your case the namespace examples.introduction is stored in the file C:\Projects.clj\examples\introduction.clj so the directory C:\Projects.clj\ should be inlcuded in the class path. When Clojure loads the namespace examples.introduction, it will try to find examples\introduction.clj in every directory (or jar file) in the class path. The error you got is an indication that no matching file could be found. On windows, the paths are delimited with semicolons, but on most other platforms colons are used. That's why most examples will use colons. If the paths in the class path contains spaces or other special characters, you should enclose the thing in spaces, like this: java -cp "C:\path one\;C:\path two\" clojure.main >From what I can tell, Rob's example should work. I'm not sure if a trailing backslash is required for directories, but you could try with and without it to see if it makes any difference. If that doesn't work, try renaming projects.clj to something without a dot in it. Also, look carefully for typos...
