[equinox-dev] Ruby XMLRPC client for the XMLRPC JMX Connector

["J B" <moatas@xxxxxxxxx>]

I am trying to connect to the JMX XMLRPC connector using a ruby client
and am running into issues.  I am using the following code:

require "xmlrpc/client"
server = XMLRPC::Client.new( "localhost", "/", "8119")
begin
  result = server.call("getMBeanCount")
  puts "Found #{result} bean(s)"
rescue XMLRPC::FaultException => e
  puts "Error: "
  puts e.faultCode
  puts e.faultString
end

I get a Fault code of 0, and the equinox console spits out the following trace.

Anyone have any suggestions?  I would love to be able to use this
festure to allow any XMLRPC capable language to interact with the JMX
server.
