help!!I can't see the "jde"menu

[root]

My emacs is 20.3.1.And i use jde2.1.6beta.
The path of jde2.1.6beta is /usr/local/jde.
I have configed the file .emacs below.
(setq load-path
       (nconc  '(
                             "/usr/local/jde"
                         )
                            load-path))
(require 'jde)

or

(setq load-path
       (nconc  '(
                             "/usr/local/jde/lisp"
                         )
                            load-path))
(require 'jde)



But when i open the file test.java,i  can't see the "jde" menu.Why?
