Hi Peter,
Pack a Ruby application into an executable jar file. Jarbler creates a self executing Java jar file containing a Ruby application and all its Gem dependencies. The included Ruby program is directly executed inside the JVM using the JRuby runtime jars.
I think I remember you struggling with Warbler at some point - is this essentially similar, or are there key differences? The JRuby team also recently did a lot of work to make Warbler usable again. Best regards, Mohit.
