There is lots of library type functionality for this sort of thing in
Java. Some of it is used in the JDE. The JDE already uses Cedet.

An similar aproach I worked on a bit was this:

- Make EDE realice a pom.xml is a Maven project file 

- Hook up Cedet to the Maven via Clojure

EDE is a project support facility in Cedet. Maven is a project
dependency and build tool facility for Java. Clojure is a lisp-like
interpreter on top of Java.

The thing I wanted to achieve was:

- user downloads emacs

- installs "java-maven-cedet-adaptor.el" (or whatever) from elpa

- opens a random src file in his existing java project shared with
eclipse developers also using maven

- experiences the bliss of instant working completion and tag navigation
in Emacs, thus stunning eclipse users, otherwise accustomed to Emacs
users mumbling and pretending completion and navigation is only for n00bs.

It is entirely doable and not so far off.
