Subject: Re: XML-RPC WEBrick problem (error during method invocation)

I attempted a fresh start without using WEBrick.
Does this seem more logical? I am still stuck on the http error 500 and 
the output is still on the serverside. I also don't quite understand 
what is a NilClass?

my server:
require 'xmlrpc/server'
require 'C:\Users\Moog\Ruby\MyMethods.rb'

 class Server

    @manager
     def initialize()
       @manager = MyMethods.new
     end

     def help
      @manager.help
     end
 end

 server = XMLRPC::Server.new(8080, "127.0.0.1")
 server.add_handler("xmlrpc", MyMethods.new)
 puts "Server ready!"
 server.serve

my client:
require 'xmlrpc/client'
server = XMLRPC::Client.new("127.0.0.1", "/RPC2", 8080)
server.call("xmlrpc.help")

MyMethods.rb:
class MyMethods

  def help
    puts "help"
                puts "help"
    puts ""
    puts "help"
  end
end


my output server side:
[2010-10-07 15:12:38] INFO  WEBrick 1.3.1

I'm guessing here, i'm stuck at the same situation as before, i am 
missing something on the server-side, but i really cannot see it. I have 
already spent many sleepless nights trying to figure this out.
Could you give me another hint? You don't have to give me the solution 
:D i would love to have the facepalming moment myself :D

thanks again for all the assistance already.
