Problems on installation of JDE 2.2.8

[Jean-Jacques Gourrier]

I installed JDE with the correct Paths (not compiled) and i followed the way to run it (the minimal _emacs file) :   ;; This .emacs file illustrates the minimul setup ;; required to run the JDE.   ;; Set the debug option to enable a backtrace when a ;; problem occurs. (setq debug-on-error t)   ;; Update the Emacs load-path to include the path to ;; the JDE and its require packages. This code assumes ;; that you have installed the packages in the emacs/site ;; subdirectory of your home directory. (add-to-list 'load-path (expand-file-name "D:\Developpement\Emacs\Package\jde\lisp")) (add-to-list 'load-path (expand-file-name "D:\Developpement\Emacs\Package\semantic")) (add-to-list 'load-path (expand-file-name "D:\Developpement\Emacs\Package\speedbar")) (add-to-list 'load-path (expand-file-name "D:\Developpement\Emacs\Package\elib")) (add-to-list 'load-path (expand-file-name "D:\Developpement\Emacs\Package\eieio"))   ;; If you want Emacs to defer loading the JDE until you open a ;; Java file, edit the following line (setq defer-loading-jde nil) ;; to read: ;; ;;  (setq defer-loading-jde t) ;;   (if defer-loading-jde     (progn       (autoload 'jde-mode "jde" "JDE mode." t)       (setq auto-mode-alist      (append       '(("\\.java\\'" . jde-mode))       auto-mode-alist)))   (require 'jde))   ;; Sets the basic indentation for Java source files ;; to two spaces. (defun my-jde-mode-hook ()   (setq c-basic-offset 2))   (add-hook 'jde-mode-hook 'my-jde-mode-hook)     But i still have the message on the emacs screen displayed "Invalid escape character syntaxt". The version of my pachages are : jde 2.2.8 semantic 1.4 beta 12 speedbar 0.13a elib 1.0 eieio 0.16   Thanks for any help
