Warbler-built code containing certain JRuby gems doesn't appear to work

I noticed that some of my more basic code built with warbler executed
just fine, while other programs simply didn’t work. After a bit of trial
and error and playing with the code, this is what I discovered:

The following code works fine when built with warbler:


require ‘rubygems’

puts “Hello World”
gets


However, if I add ANY of the following ruby gems to the above code and
build it with warbler, I am unable to run the resulting JAR file or the
subsequently converted EXE file.


spreadsheet
ole/storage
jruby-win32ole


Has anyone else here ever faced this issue and does anyone know whether
there is a workaround or a solution for this?

Just bumping this thread in case anyone knows the solution to this.

Can you post versions of Warbler, JRuby, etc. and also post the output
of “jar tf mywar.war”?

Warbler Version: 1.3.2
JRuby Version: 1.5.1

I’m not sure what you mean by [post the output of “jar tf mywar.war”].
I’ve attached the JAR file created by warbler along with this post for
your reference if that helps.

the gem spreadsheet for example is not inside your jar file.

2 possible solutions:

  • tell warbler to include them (look at the man page, I believe it’s
    possible)
  • include gems and specifications inside the jar file itself: you need
    to create gems and specifications folders on top, and put inside
    respective folders from your gems and specs. This is what I usually
    do.

Thanks for the solutions, although I’m a complete programming noob and
can’t seem to figure out how to implement them. Do I need to copy-paste
the gems somewhere? If so, how?

I looked online and found the following code:


source “http://gems.github.com
gem “spreadsheet”

Do I need to add this somewhere, say, in the spec folder? If so, what
should I name the file in that folder and is there anything else to be
done?

You can try with something like this in your warble.rb file:

config.gems[“actionpack”] = “2.3.8”

Obviously, change the gem and version to match your gem.

I added the details in the warble.rb file but to no avail. I’m not sure
whether I did it correctly so I’ve attached the file along with this
post. The added code is at the end of the file.

I still cannot see the gems in the JAR file after recreating it.
