Hello,

I am trying to run a small test case here and it times out on me all the  
time:  
Here is my code:

require ‘xmlrpc/client’  
require ‘pp’

applicationName = “Demo AcceptanceTestingApp”  
server =  
XMLRPC::Client.new2(“[https://vwtest.oas.psu.edu/isapi/gi.dll/rpc2](https://vwtest.oas.psu.edu/isapi/gi.dll/rpc2)”)  
result = server.call(“blank”,“whatever”,applicationName)  
pp result

The call just times out even though I have other programs in Python, CF  
working just fine.  
Is there any way to see what ruby sends to the server? I tried using  
HTTPAnalyzer, but it captures nothing.  
I am wondering if it even sends anythign?

If one side is Linux, try

tcpdump -i eth0 -n -s0 -X tcp port 80

or install wireshark and use that (for a fluffy GUI interface).

If both sides are Windows, you can install wireshark, or its older  
cousin  
ethereal.

HTH,

Brian.

module XMLRPC  
class ConversationSavingClient \< Client

```
 def do_rpc(request, async=false)
   response = super(request, async)
   @conversation << [request, response]
   return response
 end

```

end  
end

client = XMLRPC::ConversationSavingClient.new(‘[time.xmlrpc.com](http://time.xmlrpc.com)’,  
‘/RPC2’, 80)  
client.call(‘currentTime.getCurrentTime’)  
puts client.conversation.to\_yaml

## $ ruby xmlrpc\_conversation.rb

- 
  - | \<?xml version="1.0"

?\>currentTime.getCurrentTime

- |\<?xml version="1.0"?\> 

\<dateTime.iso8601\>20070305T13:43:22\</dateTime.iso8601\>

Is that helpful?

HELPFULL!?!! Helpful is not the word. You should be elevated to god-like  
status :).  
Your solution exposed my embarrasing stupidity and lack of attention  
plus it taught me something.  
Ruby does force me think harder at stuff and certainly didn’t try hard  
enough.  
Thanks again.

Brian: Yours helped me too. That’s how I figured out that there was no  
communication except certificate handshake. HTTPAnalyzer isn’t able to  
capture anything for whatever reason.
