Re: [jruby-user] How to use custom class files in Rails?

I don't have a "right" answer for you, but I what I can share with you is
what has worked for me.

My team uses torquebox and sinatra for our web services.

We started by just directly interacting with Java APIs in our Ruby classes
but kept bumping into issues with exception handling and type errors. When
it comes time to deal with incompatible library upgrades, some of the APIs
are so complex I felt like we were rewriting the application.

We have now tried minimizing/isolating all of our interactions with Java
code in our application. We started writing custom java code that provides
a narrow interface in order to expose the functionality we need and then
package it up into a shaded jar with dependencies.

As far as delivery is concerned, we used to just deploy the shaded jars in
vendor/jars but again ran into some issues with respect to managing those
libraries. A few months ago we decided to move our application
functionality into gems and deliver the shaded jars as part of those gems.
We hope to take advantage of the jar-dependencies project someday but
haven't tried it yet.

We also haven't tried writing custom JRuby extensions so I don't have any
feed back there.
