Many academics consider a series of programming languages to be a sub-set of features available in Lisp, a testament to Lisp's power. These series of posts by Bill Clementson explore Lisp in the context of Java's Virtual Machine using Clojure, and include the background behind this project, as well as how to set up Clojure with Java.

Besides Bill Clements' posts, the post by Hans Hübner (netzhansa.blogspot.com/2008/10/trying-clojure.html) is very interesting read. In my current job we use Common Lisp and it is a great programming language. But, as a Java programmer I'm also a bit disappointed by the lack of frameworks and libraries, at least out-of-the-box. Clojure or other JVM based lisps could be a solution to this problem.
