CHAPTER 22: Scripting Support in Spring > Scripting Support in Java
Scripting Support in Java
Starting with JSE 6, the Scripting for the Java Platform API (JSR-223) is bundled into the JDK. Its objective is to provide a standard mechanism for running logic written in other scripting languages on the JVM. Out of the box, JDK 6 comes bundled with the engine called Mozilla Rhino, which is able to evaluate JavaScript programs. This section will give you an introduction to the JSR-223 support in JDK 6.
In JDK 6, the scripting support classes reside in the package javax.script. First let's develop a simple program to retrieve the list of script engines. Listing 22-1 shows the class content.
Listing 22-1. Listing Scripting Engines
package com.apress.prospring3.ch22.jsr223;
import javax.script.ScriptEngineFactory;
import javax.script.ScriptEngineManager;
public class ListScriptEngines {
public static void main(String[] args) {
ScriptEngineManager mgr = new ScriptEngineManager();
for (ScriptEngineFactory factory : mgr.getEngineFactories()) {
String engineName= factory.getEngineName();
String languageName = factory.getLanguageName();
String version = factory.getLanguageVersion();
System.out.println("Engine name: " + engineName + " Language: " + languageName + " 
version: " + version);
}
}
}
