Vim omnicompletion for Java

java autocomplete vim omnicomplete

I've read heaps of blogs on Vim's supposedly great omnicompletion, and yet no matter what I do I can't get it to work satisfactorily. It took me ages to figure discover that the version of ctags that is preinstalled on my system was the emacs one, and didn't have the --recurse option, but now that I've run ctags-exuberant on my copy of the OpenJDK sources to attempt to get some kind of code completion going, Vim hangs whenever I try to invoke it with [C-n] or [C-p].

All I really want is something that works like the code completion in Eclipse; I like Vim as an editor, but Eclipse just has those extra features out-of-the-box which Vim seems to fail with. Eclipse with a vi-mode plugin wasn't particularly useful to me, and it is too much of a memory and CPU hog to be of any use; eclim doesn't quite like me either.

Can anyone suggest a simpler way to get some kind of code completion working in Vim that actually works?

Here is a "JDE" feature for vim: http://www.vim.org/scripts/script.php?script_id=1213 One of the listed features is "Code completion ( working for java and jsp,taglib,html,xml,xsl,xsd) (VIM 7.0 required) "

And here is a Java autocompletion script: http://vim.sourceforge.net/scripts/script.php?script_id=1785

This one isn't Java, but I found it to be quite clear and understandable; perhaps it might be worth reading. Here is a recipe on setting up autocompletion for Drupal. A custom AWK script builds an autocompletion dictionary for vim. http://www.thingy-ma-jig.co.uk/blog/18-08-2009/drupal-autocomplete-vim

Good luck.
