Issue with the gems using jruby-complete

Ruby JRuby
1

Hi all,
I’ve got another problem with the rubygems which I want to use
jruby-complete.jar

I have the jruby-complete.jar file which has rails, active record jdbc
adapter with h2 adapter inside the jar.

I have this simple test program

$LOAD_PATH << ‘META-INF/jruby.home/lib/ruby/site_ruby/1.8’

require ‘rubygems’
require ‘mongrel’
require ‘activerecord’
gem ‘activerecord-jdbc-adapter’ # ERROR THIS LINE
gem ‘activerecord-jdbch2-adapter’

When I look inside the jar file (the META-INF/…) I can see all the
required directories there.

I appreciate your comment to resolve this issue.

Cheers,

-A

Hi Ali, unfortunately Rubygems expects the gem directory structure to
be on the filesystem ($GEM_HOME/gems, $GEM_HOME/specifications etc.),
and in JRuby we don’t yet have a virtual filesystem abstraction that
lets you do something like
File.open("jar:file:///path/jruby-complete.jar!/META-INF/jruby.home/lib/ruby/gems/1.8).

If you want to bundle gems inside of the complete jar, your best bet
is to not use Rubygems at all, but just bundle the code either inside
the root of the jar, or in a subdirectory in the jar that you can add
to the load path like you did for site_ruby/1.8.

Cheers,
