I use Clojure to write a couple of scripts and hacks but what if you want to use it to substitute my Java code (like Spring beans, beans in general, Servlets)?
http://clojure.org/compilation Any special points I should pay attention to?
Clojure provides compilation facility, for example:
Any idea how integrate this facility into Ant or Maven?
Have you taken a look at Leiningen? It's a build tool for Clojure that's very easy to use and wraps up Maven under the hood (I'm not sure of the exact details - I'm an ant guy, not a Maven guy). Specific things Leiningen can do include running tests, compiling Clojure code, packaging it into a JAR file and so on.
