Emacs and JDEE : opinions sought.

[Richard Riley]

Could someone familiar wit Java advise me about the status of JDEE? Is
it usable? How well integrated is it with Semantic for example for Java
class method/member completion possibly using ac-source-semantic with
auto-complete?  Basically, is it worth the effort of learning and using
Emacs for Java?

Any hints or tips with regard to Java development in Emacs much
appreciated as I really want to stay from eclipse if at all possible.

I realise I could download it and try it but not being a seasoned Java
programmes I feel I'm not really equipped to rate it.

regards
