Rhino (JavaScript) is implemented in the Oracle JDK/JRE by default.
With this code you can see what scripting languages are available in your JDK:
import java.util.*;
import javax.script.*;
public class A {
public static void main( String[] args ) {
ScriptEngineManager mgr = new ScriptEngineManager();
List<ScriptEngineFactory> factories = mgr.getEngineFactories();
for (ScriptEngineFactory factory : factories) {
System.out.println("ScriptEngineFactory Info");
String engName = factory.getEngineName();
String engVersion = factory.getEngineVersion();
String langName = factory.getLanguageName();
String langVersion = factory.getLanguageVersion();
System.out.printf("\tScript Engine: %s (%s)%n", engName, engVersion);
List<String> engNames = factory.getNames();
for(String name : engNames) {
System.out.printf("\tEngine Alias: %s%n", name);
}
System.out.printf("\tLanguage: %s (%s)%n", langName, langVersion);
}
}
}
