Ruby and Java Running in JavaScript

John Resig is reporting on his blog that a recent trip to Tokyo opened up some very interesting JavaScript projects to him that haven't met with widespread popularity outside of Japan yet. "One project, in particular, really caught my eye. It's called Orto and is an implementation of the Java Virtual Machine (JVM) in JavaScript. This means that you can take an existing Java application, compile it to bytecode, run it through Orto (which produces the JavaScript, and embed it in a web page. While it doesn't provide the full capabilities of most Java code it does provide enough to make for some interesting demos." In a separate post he also detailed how the HotRuby project is allowing a Ruby VM to run in a browser using JavaScript or even indirectly using ActionScript in Flash.

Thanks for the info!

I understood that Java was an OOL, but failed on the whole JS understanding.

Thanks to your reply, I now know enough to differentiate the two: In other words: Java !=JS. I sort of get it and heartily thank you for the informative reply.

I sincerely hope the /. moderators give you some 'informative +' love.
I did not really get the diff, but see now I have more learning and research to do, as I do want to 'get it'.

I guess the whole 'Java' vs. 'Javascript' is confusing to n00bs (or 'us morons') since they both contain the (unrelated) root word:java.

Again thanks for a respectful and informative reply that can forward the conversation constructively...*can be a rare thing here on /.*... based on that, I feel compelled to add you to my 'Friend's' list here, so be forewarned if your pref's advise you on the change/message. (have not checked your user page,etc.)
