We’re using Warbler to deploy our application to JBoss. The server seems to start fine, but when a request is sent to the application we get the following error:
...
JRuby-Rack startup
No such file to load -- lib/mylib
....
As you can see it seems to be crashing out when trying to load the mylib.jar, which is Java library we are using in the user.rb class. I’ve tripled checked that the mylib.jar file exists in the myapp/lib directory and also that it gets successfully packaged by Warbler (it lives in WEB-INF/lib/mylib.jar).
Please Note: I downgraded JRuby-Rack to 1.0.10 after running into the issue detailed here – NoMethodError: relative_url_root when deploying rails app on tomcat. So perhaps the issue has something to do with this?
I’m at a loss as to what’s going on. Any ideas?
Other details that might prove useful:

How are you requiring your jar.
if it’s
try changing it to
