Can a Ruby script in JRuby use my Java classes if I haven't shared them with it?

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?

是的，根据我的回答 ：如果MyClass在你的类路径/ $LOAD_PATH ，JRuby会在你java_import时把它拿起来。
