Help with university assignment

So, we are supposed to create an xml-rpc based event manager using 2-3
programming languages. C#, Java, Ruby.

I opted for ruby(i did this course last year but the dropped out).
So, this time i am really trying.
The code is not the actual problem for me.

It is the testing.

Right now i am attempting this: my usual machine(windows 7), and a
virtual machine running windows xp.

in both there is the same program:

require “xmlrpc/server”
require “xmlrpc/client”
s =

s.add_handler(“add”) do|id,date,time,duration,header,comment|
eventCounter=eventCounter+1"#{id}"+".event", ‘w’) {|f| f.write("#{date}| #{time}|
#{duration}| #{header}| #{comment}") }


s.add_handler(“delete”)do |id|
s.set_default_handler do |name, *args|
raise, “Method #{name} missing” +
" or wrong number of parameters!")

server =“”, “/RPC2”, 8080)
puts “Press 1 to add an event\n”
puts “Press 2 to remove an event of given ID\n”

while whatToDo!="-1"
  puts "Press 1 to add an event\n"
  puts "Press 2 to remove an event of given ID\n"

  case whatToDo
    when 1"add",eventCounter,"03/10/2011","sadkfdsa","not

long",“some header”,“some comment”)
when 2
puts “Input ID to delete\n”
    puts "Please input 1 or 2"

  end"delete","2")   Delete example




One one computer i am running port 8080, on the other 8090 for the

I was also wondering, which ip do i have to write? i tried but
that ofcourse executes locally.
I tried and .8 depending on the machines(their
corresponding ip for the router).

I also tried my web ip, but ofc that is the same for both machines cos
i’m behind 1 router.

Can some1 please help me in this part? If i get past this, i can test my
code everytime i plan something. This ofcourse means i can do my

Ofcourse i opened the ports 8080 and 8090 in my router.

I have also attempted running the example code for xmlrpc server and
require “xmlrpc/server”

s =

s.add_handler(“michael.add”) do |a,b|
a + b

s.add_handler(“michael.div”) do |a,b|
if b == 0
raise, “division by zero”)
a / b

s.set_default_handler do |name, *args|
raise, “Method #{name} missing” +
" or wrong number of parameters!")


require “xmlrpc/client”

server =“”, “/RPC2”, 8080)
param =“michael.add”, 4, 5)
puts “4 + 5 = #{param}”
rescue XMLRPC::FaultException => e
puts “Error:”
puts e.faultCode
puts e.faultString

I really have no idea what i am doing wrong. And i do understand it isnt
really a ruby question, but i really have no idea where i could ask a
question like this

If somebody can solve this, then cyber beer is yours forever :slight_smile:

The best place to ask is the fora for the virtualization solution you
are using.

A method of solution is perfect if we can forsee from the start,
and even prove, that following that method we shall attain our aim.

What software are you using for your virtual machine? it sounds like a
network configuration issue. If you use VirtualBox, just configure a
bridged connection and forward the ports properly from your host
machine to your virtual machine.

i figured out the problem. I was doing and i should
have been doing,“192.168.0.x”) after that, it was all
fine. It worked through a VM, through my WLAN at home, i will soon test
it over the net. But yea, thanks for the time spent anyway guys, i got
it all figured out now. Assignement is almost finished.
