Having myself delved into Lisp over the preceeding two years I too have 
had to figure out how to interface java libraries with Lisp programs or 
the other way around. Here are pointers to some of the more prominent tools.

jfli  - a bridge between clos and java for Xanalys Lispworks. Lets you 
instantiate and access java classes running in a jvm, from java in a 
Lisp runtime. http://jfli.sourceforge.net

Armed Bear Common Lisp - a Common Lisp compiler that targets java 
bytecode. It is being used to implement and is distributed as a part of 
the editor J. http://armedbear-j.sourceforge.net

linj - a Common Lisp look-alike language and a converter from this 
language to java that generates code that looks surpricingly close to 
well written hand written code. http://www.evaluator.pt/linj.html

jLinker - a part of Franz Allegro Common Lisp 7.0 I have not personally 
tried this one.
