JRuby + Java Web Start gems can't be loaded
-------------------------------------------
Key: JRUBY-4544
URL: http://jira.codehaus.org/browse/JRUBY-4544
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.5
Environment: Mac OS X 10.5.8, Java 1.6, JRuby 1.5.0dev
Reporter: Gonzalo Suárez
Assignee: Thomas E Enebo
I have the following simple JRuby app:
gui.rb file:
--8--
include Java
require 'rubygems'
require 'active_support'
frame = javax.swing.JFrame.new("Hello JRuby!")
frame.setSize(300, 300)
string = ActiveSupport::Base64.encode64("Hello JRuby!")
label = javax.swing.JLabel.new(string, javax.swing.JLabel::CENTER)
frame.getContentPane().add(label)
frame.setVisible(true)
--8--
I pack it in a JAR:
java -jar jruby-complete-1.5.0.dev.jar -S jrubyc gui.rb
jar cf gui.jar gui.class
I pack the required gem:
java -jar jruby-complete-1.5.0.dev.jar -S gem install -i ./gems activesupport
--no-rdoc --no-ri
jar cf gems.jar -C gems .
Then I sign the three JARs (gui, gems and jruby-complete-1.5.0.dev) with
keytool.
This is my gui.JNLP file (Java Web Start)
--8--
<?xml version="1.0" encoding="utf-8"?>
<jnlp
spec="1.0+"
codebase="file:/Users/gonzalo/Stuff/Programming/JRuby/"
href="gui.jnlp">
<information>
<title>JRuby Simple GUI</title>
<vendor>Gonzalo Suárez</vendor>
</information>
<security>
<all-permissions/>
</security>
<resources>
<j2se version="1.6+"/>
<jar href="gui.jar"/>
<jar href="gems.jar"/>
<jar href="jruby-complete-1.5.0.dev.jar"/>
<property name="jruby.native.enabled" value="false"/>
</resources>
<application-desc main-class="gui"/>
</jnlp>
--8--
Now I start the Java Web Start:
javaws gui.jnlp
Everything works fine. I tested this on Mac OS X 10.5.8 and Windows 7.
I uploaded everything to my amazon S3 bucket.
http://liquidknife.s3.amazonaws.com/gui.jnlp
(I modified the gui.JNLP with the right codebase.)
I tested it again on my Mac and this is what the Java console shows:

#### Java Web Start Error:
#### no such file to load -- active_support

It seems that gems can't be located when the code is fetched from HTTP. Any
ideas of what may be going on? Thanks for your help.
