Ruby application talking to Java application (IPC suggestions please)

Rails
1

Hi all,

I’m wondering how can I make RoR application talk to Java application
running in background. Does anyone have any experience with this kind
of stuff? Anny suggestions welcome.

I am running Ruby on MRI, and Java application will run on the same
machine but in JVM.

Thanks,
H.

Web Services; RESTFUL or otherwise. Though you can do SOAP on Rails, I
recommend picking up “RESTful Web Services” by Leonard Richardson and
Sam
Ruby.

+1 for restful web service, or perhaps run your rails app in jruby &
then you can make java calls from ruby.

Hi,

I went third route. I couldn’t use web services as I was clearly told
not to use any Java web container. I also couldn’t use jruby, as I am
dependent on some C++ libraries. Fortunately, there is nice library
Ruby Java Bridge (http://rjb.rubyforge.org/) that helped me get around
this issue and include my Java classes into project directly. Can’t
say much about resources consumption/memory leaks or stability yet,
but all looks good for now.

Thanks,
H.
