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
