Trouble installing on cygwin Xemacs

I've got Xemacs 21.4.20 running on latest cygwin on Windows Vista.

The JDE from cygwin is 1.48 according to Tools-Packages-List.

Trying to upgrade to jde-2.3.5.1 downloaded from http://jdee.sunsite.dk/

The instructions at http://jdee.sunsite.dk/install.html say to go to 
sourceforge for cedet but it looks like the versions of semantic and 
elib are more up to date on cygwin.  Also the instructions talk about 
.emacs file but what I have is an init.el file in the .xemacs directory 
with these contents -

- - - - - - - init.el  - - - - - -
(add-to-list 'load-path "c:/java/emacs/jde2.3.5.1/lisp")
(require 'jde)

(defun my-jde-mode-hook ()
  (c-set-style "bsd")
  (setq c-basic-offset 4))
(add-hook 'jde-mode-hook 'my-jde-mode-hook)
- - - - - - - - - - - - - - - - -

However Tools-Packages-List menu still shows jde 1.48 so I think the 
install is not successful.

Where am I going wrong?

TIA - Paul
