A simple approach would be dumping the representation of scheme
objects (e.g., lists) to a file:

  csi> (define my-list '((1 2 3) (4 5 6) ("a" "b" "c")))
  csi> (with-output-to-file "my-file" (lambda () (pp my-list)))
  csi> (with-input-from-file "my-file" read)
  ((1 2 3) (4 5 6) ("a" "b" "c"))

There is also the s11n egg:

PS: I don't know what Java's properties files are, I considered the
second paragraph from your message.

Best wishes,
