At least for Java (and probably most other languages) (emacs-)eclim can leverage Eclipse functionality (for Emacs, Vim, ...). So you'll get the same completion

  How do I not know about this?!?!?! Thanks for sharing the link, do you have any experience to share? Does it work well? EDIT: If this works as advertised here [1] then I am all in! [1] -- http://www.skybert.net/emacs/java/ http://www.skybert.net/emacs/java/

    It would actually be cool to have a ninite.com for Emacs configurations, where one could choose from the best pre-configured crowd-sourced Emacs versions for several use cases and platforms (e.g. web-design, Java-programming or reproducible research). Sure, extending Emacs from scratch is fun, but many people are probably reluctant having to spend many hours to achieve a good configuration because they are not guaranteed to benefit from the result.

  But you then need eclipse installed also right? I use intellij for my java needs and it makes me content the bulk of the time. Having used emacs + jdee back in the day I'm afraid of the lost hours to trying emacs+<insert hack here> again.

    Yes, that's also one of the reasons I didn't pursue this, the other one that I wanted to be able to use other peoples machines (including shortcuts etc.) as well. It's a tradeoff; Eclipse has a lot of understanding of the different languages, which seems to me is not really worthwhile to rebuild in Elisp if you can just reuse it this way.
