JACOL
The JACOL system can be used to link Java and Common Lisp applications.
From its webpage:
"JACOL is a framework for allowing Java and Common Lisp to interoperate. It's
intended use is to enable Common Lisp to function as an extension language for Java. But, it can also be used to expose Java APIs (such as Swing and DOM) to Lisp application."
