I have trouble to invoke Ruby scripts in Java applications The following didn't work > Ruby runtime = Ruby.getDefaultInstance(null); > runtime.evalScript("puts 'hello'"); any examples???? Runtime.getRuntime().exec("jruby test.rb"); //didn't work either, no output //test.rb puts 'hello' So basically Ruby doesn't support Java. i.e. Ruby language can't invoke Java API
