- 采用 Java 实现的高级动态编程语言，编译后是 Java 的类。
- An implementation of Scheme, which is in the Lisp family of programming languages. Kawa is a featureful dialect in its own right, and additionally provides very useful integration with Java. It can be used as a “scripting language”, but includes a compiler and all the benefits of a “real” programming language, including optional static typing.
- Implementations of other programming languages, including XQuery (Qexo) and Emacs Lisp (JEmacs).
