JSR 223: Scripting for Java

As Charles Nutter suggested, I decided to try javax.scripting API. The Java 6 Revealed book has a nice chapter on JSR 223 and also an example of Pnuts integration with JVM.
I have downloaded the other engines from java.net. It seems that for my SOC project it is reasonable to use Java 6. Virtually it will be possible to write plug-ins in any scripting language for which the engine is available. We could even use combination of many languages, just selecting the relevant engine by name or file extension:

    ScriptEngineManager m = new ScriptEngineManager();
    ScriptEngine groovyEngine = m.getEngineByName("groovy");
    ScriptEngine jrubyEngine = m.getEngineByName("jruby");

The full list of the scripting engines is available at java.net
