SOAP4R comes standard with Ruby 1.8.x
(for a brief introduction have a look at: http://www.simplesiteuk.com)

I haven't heard of any RMI lib freely available in native Ruby 

There's also RJNI: Java binding for Ruby through JNI 
http://thekode.net/ruby/rjni/index.html
(though unsupported at the moment, would be interesting for someone to
pick it up)

You may consider JRuby can be a good option for some projects:
http://jruby.sourceforge.net/

There are some other JNI bindings available, can't recall the names
now, someone will probably help adding to the list in this thread.
