Rhino is an open-source implementation of JavaScript written entirely in Java. It is typically embedded into Java applications to provide scripting to end users. It is embedded in J2SE 6 as the default Java scripting engine.
Rhino contains
- All the features of JavaScript 1.7
- Allows direct scripting of Java
- A JavaScript shell for executing JavaScript scripts
- A JavaScript compiler to transform JavaScript source files into Java class files
- A JavaScript debugger for scripts executed with Rhino
Shell
$ java -jar js.jar
