(require 'ecb)
(custom-set-variables
  ;; custom-set-variables was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 '(ecb-fix-window-size (quote width))
 '(ecb-layout-name "left1")
 '(ecb-layout-window-sizes (quote (("left9" (0.32857142857142857 . 0.9791666666666666)))))
 '(ecb-options-version "2.32")

3. Install autocomplete

http://www.emacswiki.org/emacs/AutoComplete

- git clone https://github.com/auto-complete/auto-complete

-git submodule init; git submodule update

- make install

- input directory name as ~/.emacs.d/auto-complete

- move libs folder such as popup, fuzzy and ert from auto-complete's source directory to ~/.emacs.d

add follow script to .emacs

;;auto-complete

(add-to-list 'load-path "/Users/kwangjo/.emacs.d/auto-complete")

(add-to-list 'load-path "/Users/kwangjo/.emacs.d/popup");

(require 'auto-complete-config)

(require 'popup)

(ac-config-default) 

4. Install CSCOPE

 - cscope should be installed using brew or make binary
 - Download source file from http://cscope.sourceforge.net
- you should make cscope.files on project directory
find . -name "*.java" > cscope.files

- emacs command using like below

5. using eTags

 - you can make navigate tags (like ctag with vi) using following command
find /usr/src/linux -name '*.[csSh]' | xargs etags

you can using follow script, navigate like vi.

(fset 'find-next-tag "\C-u\256") ; macro for C-u M-. 
(fset 'find-prev-tag "\C-u-\256") ; macro for C-u - M-. 
(global-set-key "\M-]" 'find-next-tag) (global-set-key "\M-[" 'find-prev-tag)

You can find tag using M-. and navigate using M-[ and M-]
