jRuby Glassfish v3 dispatcher error

Question

hi all.

i have ubuntu 8.10, running glassfish v3 (not prelude). first deployment of any jruby on a glassfish v3 SERVER (not the gem).

i have deployed the app using the 'choose folder' method, rather than the asadmin deploy method, though i have also tried that.

i get the following error message:

this is very bizarre. i can't find much on it, but i know from experience that dispatcher was removed and one can no longer use ruby on rails apps with mongrel. in this instance, with jruby in place and glassfish v3, i have no idea what is going on. why is it even looking for dispatcher?

any tips on my config would be great. what am i likely missing? shouldn't glassfish be treating it as a rack application and this problem NOT be occuring.

also note, if i run the app with jruby in WEBrick, it's all good.

thanks!

Answer 1

It looks like the GF v3 JRuby scripting container is expecting to load "dispatcher" and thus is probably not Rails 3 ready. Given what I've heard from Oracle about scripting support inside V3, I'm not sure you'll see a fix for this soon.

A better option for deploying inside V3 would be to use Warbler to create a war file and deploy that.
