I'm guessing I missed some install, but I can't find out what because
the error.

OSX     ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]
RHEL4 ruby 1.8.3 (2005-09-21) [i386-linux]

 ERROR LoadError: no such file to load -- rexml/namespace
where do I get that?

same script teaching myself xmlrpc on both OSX and RHEL4

server:

#!/usr/bin/ruby
require 'webrick'
require 'xmlrpc/server.rb'

# create a servlet to handle XML-RPC requests:
servlet = XMLRPC::WEBrickServlet.new
servlet.add_handler("upper_case") { |a_string| a_string.upcase }
servlet.add_handler("lower_case") { |a_string| a_string.downcase }

# create a WEBrick instance to host this servlet:
server=WEBrick::HTTPServer.new(:Port => 9090)
trap("INT"){ server.shutdown }
server.mount("/RPC2", servlet)
server.start

Client:

#!/usr/bin/ruby
require 'xmlrpc/client'
server = XMLRPC::Client.new("127.0.0.1", "/RPC2", 9090)
puts server.call("upper_case", "The fat dog chased the cat on Elm
Street.")
puts server.call("lower_case", "The fat dog chased the cat on Elm
Street.")


running this on linux I get
