Hi, Is it possible to upgrade the javascripts bundled with Rails? Can I just download the latest version from [http://script.aculo.us/](http://script.aculo.us/) and overwrite the ones in my public/javascript folder? Or would this break stuff? Cheers, Jeroen ---

Aaaaaaah I see what you mean now, and you’re right. ---

Coming from a WebObjects/Objective-C background, I’ve never been a fan of Java so when I first discovered Rails I was quite pleased for all the same reasons that it’s generated so much buzz so quickly. However, having worked in Java for the past few years out of necessity, the one concern that I have in using RoR in my professional life is that as lousy as the Java language is, there are a lot of good commercial and open source frameworks available for it. I’d hate to lose the ability to rely on some of them for my projects (obviously there’s a lot of crap out there too, but that’s neither here nor there). I’m curious whether this has been issue for anyone working in Rails. Have you come across problems that there were Java frameworks available to address that don’t yet exist in Ruby? How about using Java classes from Ruby using rjni, JRuby or some other solution? Is this something that is currently supported and if so how well does it work? If not, is it something that is actively being worked on? I’m skeptical of this approach based on my experience with an earlier version of the WebObjects application server that was written in Objective-C but allowed you to write your application in Java using Apple’s proprietary Java/Objective-C bridge. It mostly worked, but the performance wasn’t so great, there were memory leaks and every once in awhile you’d get strange unexplained exceptions. Thanks, Bruce ---

Bruce, if you don’t find what you need such that you may continue using Rails and your favorite Java thingy, you may want to consider Sails ([www.opensails.org](http://www.opensails.org)). It gives you ‘the spirit of Rails in Java’, if I may be so bold. We are using it on our second major project. It continues to improve almost every day. Sorry - ActiveRecord is not available there, though we are working on Prevayler and Hibernate 3 persistence apis that will make web- application life in Java a bit more bearable. adam williams [http://rubyeclipse.sourceforge.net/](http://rubyeclipse.sourceforge.net/) [http://www.opensails.org](http://www.opensails.org)
