Having used Rails myself I wanted to check this out and play with it. I'm having some trouble just loading the clj_record/core.clj file though:
1:1 user=> (load-file "clj_record/core.clj") java.lang.Exception: Unable to resolve symbol: db in this context (core.clj:19) I'm sure it's something I'm doing wrong but I do have derby.jar on my classpath.
