Question

If I have a Ruby script executed by ScriptingContainer of JRuby in my Java application, is the Ruby script capable of accessing or making use of a class I have defined in my Java application if I haven’t shared anything with the script?

By sharing this is what I mean:

ruby = new ScriptingContainer(LocalVariableBehavior.PERSISTENT);
ruby.put("main", MyClass.class);
ruby.runScriptlet(readFile("Test.rb"));

As you can see, I am sharing with the Ruby script a variable called main, whose value is MyClass.class.

If I don’t share anything, is the Ruby script still capable of using MyClass in my application?

Answer 1

Yes, as per my answer there: if MyClass is on your classpath/$LOAD_PATH, JRuby will pick it up when you java_import it.
