CLplusJ
CL+J is an exact, safe and complete Common Lisp interface to Java through JNI. In CL+J, Java methods are seen as normal Common Lisp functions with a somewhat different naming convention and Common Lisp functions can be exposed to Java as native methods. CL+J uses CFFI to accomplish this.

Current version of CL+J is 0.3.
