Try this in your .emacs file:

(defun jde-import-fixit ()
  "Combines jde-import-all, jde-import-kill-extra-imports and
jde-import-organize into one easy function call.  Emulates
eclipse's CTRL-SHIFT-O."
  (interactive)
  (jde-import-all)
  (jde-import-kill-extra-imports)
  (jde-import-organize)
  (save-buffer))
