Jruby and jQuery don't play well together

Ruby JRuby

Hello

Hello I am currently using:

* Mac Os X 10.6.5
* Netbeans 6.9.1 (with embedded JRuby 1.5.1)
* JDK6u17
* GlassFish Gem 1.0.2
* Rails 3.0.3

I want to user jQuery and CKeditor in my project.

After I install jquery-rails gem and ran command
“rails g jquery:install”
somethings go wrong.

Output:

  remove  public/javascripts/controls.js
  remove  public/javascripts/dragdrop.js
  remove  public/javascripts/effects.js
  remove  public/javascripts/prototype.js
fetching  jQuery (1.4.3)

identical public/javascripts/jquery.js
identical public/javascripts/jquery.min.js
fetching jQuery UJS adapter (github HEAD)

Any idea how to fix that?

I would be grateful for the help.

It works with GlassFish Gem or Warbler?
When there will be stable version?
Is there an alternative way to install jQuery on JRuby?

I use 1.6 RC2 with warbler and it works just fine.

AS to the stable version… I think/hope it’s imminent but the Jruby
core team would know better.

At the very least you could use the latest 1.5 release:
http://jruby.org/download
1.5.6 which I’ve used with warbler… I haven’t used Glassfish in a long
while.

Hi,

You could avoid installing the gem, and put in your project the rails.js
and
jquery.min-VERSION.js manually.
The following page GitHub - rails/jquery-ujs: Ruby on Rails unobtrusive scripting adapter for jQuery has all the
information you need to install everything manually.

Ok. I just installed manually jquery and jquery-ui. I also followed
“Manual installation” guide from github. Problem fixed.
