I believe this is not caused by any problems with the debugging environment.

Instead you appear to not have the clojure jar on your classpath.

I would recommend you explicitly launch java with

java -cp "H:\path\to\clojure.jar"

plus any additional arguments of course.

if this is still not working for you, please post the exact command
you are using to invoke java,
as well as a listing of all jars on your classpath, and I'll try to
help some more.

Good luck,
