I’ve been tasked to investigate using Ruby on Rails with Java  
integration, use of java libraries and being deployed on tomcat/jboss/  
oc4j

JRuby might seem like the obvious choice, but I still need to know the  
limitations of Ruby integrations with Java.

Any information would be appreciated, google keeps giving my Jruby.

You’re on the wrong forum. You need to ask this question on a JRuby  
forum.

Are you sure?

I’m asking about the limitations of Ruby on Rails (not JRuby on Rails)  
integrating with Java.

I found ‘Ruby Java Bridge’, so that Ruby can use Java libraries.

I have been asked to investigate the possibility of using RoR, on top  
of an existing java infrastructure. (but specifically not JRuby)

Have you looked for a forum for the Ruby Java Bridge? Ruby on Rails has  
nothing to do with Java so this question is still off-topic for this  
particular forum IMHO.

If there is no specific forum for the Ruby Java Bridge, then this  
question still belongs on the general Ruby forum since that technology  
has no relation to the Rails framework.

Although I know you’re not looking for JRuby on Rails specifically, you  
still might get better responses from the JRuby forum. At least those  
watchers are somewhat interested in running Ruby on the Java VM.

I’m simply trying to direct your question to the proper forum, and I  
don’t believe this is it.
