Can JRuby invoke Java APIs?? For example, if I want to invoke Ruby
scripts from Java application. And the Ruby script will invoke Java
APIs, is it possible??
For example, Beanshell script is able to do that. Thanks.

Not sure if Ruby is a java scripting language

Please read:

Ruby is a language independent from Java.

Please read:

Yes, invoking Java APIs is one of the main purposes for JRuby. To use
JRuby from within a Java application you can either use the Bean
Scripting Framework, or just access JRuby directly.

There are a few docs on how to access Java APIs at
http://jruby.sourceforge.net/.

Ruby isn’t, but JRuby is. :slight_smile:
