A simple code to show the script engines installed in your system.
As it uses the JSR-223 you need at least java 6.
import javax.script.ScriptEngineManager;
import javax.script.ScriptEngineFactory;
import java.util.List;
public class ListEngines {
public static void main(String[] args){
ScriptEngineManager manager = new ScriptEngineManager();
List engines = manager.getEngineFactories();
for(ScriptEngineFactory engine: engines){
String name = engine.getEngineName();
String lang = engine.getLanguageName();
String ver = engine.getLanguageVersion();
System.out.println(name+" "+lang+" "+ver);
}
}
}
$ java -version
java version “1.6.0_0”
OpenJDK Runtime Environment (build 1.6.0_0-b11)
OpenJDK Client VM (build 1.6.0_0-b11, mixed mode, sharing)
$ javac ListEngines.java
$ java ListEngines
Mozilla Rhino ECMAScript 1.6
For now I just have Rhino ECMAScript (JavaScript) engine accessible that comes with Java 6. I’m trying now to call Jython and JRuby code.
