i can't install flymake

HI all:
   when i install jde-flymake, i just do:


(load-file (expand-file-name "~/emacs/site/jde-flymake.el"))
(require 'jde-flymake)

(setq flymake-allowed-file-name-masks (quote ((".+\\.java$" flymake-jde-jikes-java-init flymake-simple-java-cleanup flymake-get-real-file-name))))


(define-key jde-mode-map [M-f7]         'flymake-goto-prev-error)
(define-key jde-mode-map [M-f8]         'flymake-goto-next-error)
(define-key jde-mode-map [M-f12]        'flymake-save-as-kill-err-messages-for-current-line)


But when M-x flymake-mode , result is: 
    Flymake:no builefile(makefile) found for e:/xxx/Test.java. Flymake will be switch.....

    how to resolve it? thanks.

    	Peter
