Perhaps start a thread on the JRuby mailing list and we can try to figure out how to make it work together? I've never tried using MIDI-in myself, but it ought to work as easily.

Thanks for that! Is there any way to get MIDI-in working in such an easy way, too? Trying to figure it out myself, but not sucessful yet... The JRuby MIDI-example is great. Thanks for that!

You can post things to the wiki, which is probably the best way, or post your blog entries to the JRuby list and we'll try to start aggregating a list of them somewhere. Certainly!

I use jruby on a regular basis for several projects in a corporate environment. Each of these applications use jruby to interact with other live java app servers, using third party java libraries, and also C libraries. ~jrubyist (Dan Tylenda-Emmons) Can I contribute to the list of examples?

There are bridges from MRI to Java, but they're nowhere near as seamlessly integrated as JRuby's Java integration.

There are plenty of languages that run on the JVM that call Java code seamlessly. Groovy, Scala,, to name a couple. In fact, why would you put a language on the JVM if not to have access to the Java SDK? <quote>One of the most powerful features of JRuby (and one thats unique to JRuby)" is the fact that you can call out to any Java library as it if were just another piece of Ruby code</quote>
