Neocomplete and Eclim don't work together - eclim

Question

with the default set up, there nothing shows about the auto completion,either no autocomplete shows up nor <C-X><C-U> key, the later shows "pattern not found", Is there anyone can tell me how to make it working?
here my vimrc file:
set nocompatible
syntax on
set laststatus=2
set encoding=utf-8
set guifont=Anonymous\ Pro\ for\ Powerline:h13
let g:Powerline_symbols = 'fancy'
if has("gui_running")
set guioptions=egmrt
set transparency=10
set guifont=menlo:h14
endif
imap jj <Esc>
set autoindent
set tabstop=4
set shiftwidth=4

Put this in your vimrc
let g:EclimCompletionMethod = 'omnifunc'
