ok, i want to be able to send some data from my rails app to a CRM. The library that defines the API for talking to the CRM is written in java. I got JRuby working, which is pretty cool, but to my understanding i would have to convert my ruby on rails app to a jruby on rails app which, as far as i''ve understood, is different deal altogether and would be set up more like a java server that fakes itself into thinking its ruby on rails.... i don''t want to complicate things any more than i have to, but i really don''t want to write everything in Java just because i''ll be making a few calls to the crm. Enter YARB (yet another ruby bridge), this seems a lot less heavy and i was gonna drop JRuby for this because it seemed like it ''just works TM''.. problem: i can''t get it to recognize any of the functions in my crm.jar !! i''ve tried putting it just about everywhere, but the java core lib area itself (and i don''t want to do that). Admittedly i''m not a java guru, but know the ropes sort of.. thanks in advance.. if you have any experience with bridging these languages let me know! this is the main focus of my work efforts right now. stuart --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

its me again.. well i finally got yarb to recognize the libraries in my
crm.jar. the problem was simply a bad install of jdk.
the problem now..
one of the classes in the crm jar uses java.lang.reflect which is a
class for getting more info about java classes. anyways it crashes hard
with something like this:
java.lang.reflect.InvocationTargetException

i guess that reflect library is probably freaking out because its not
looking at a real Java class? anybody know a way around this?
