I am trying to understand the XMLRPC client library and how to use it  
properly. I have looked at some of the examples and they area always  
add these two numbers together. I need help in writing a client with a  
complex structure of data, lots of individual values and arrays of  
values, even some structures.

Is there an example of how to create the passed structure a nd pass  
it. Or do I pass a hash of thelements?

Arrays, Hashes, Numeric types, and simple Strings are all handled the  
same in XML-RPC. Just replace the simple data you’ve seen in the  
examples with more complex collections and it should work fine.

Ok I have tried that with the following:  
server = XMLRPC::Client.new2(“[http://websearch.ramaui.com/ramxml.php](http://websearch.ramaui.com/ramxml.php)”)  
results = server.call(“lists”,{ “dbid” =\>“dbid1113086003”, “getlist”  
=\> “district”})

and I get XMLRPC::FaultException: XMLRPC::FaultException

Also tried this:  
results = server.call(“lists”,{ :dbid =\>“dbid1113086003”, :getlist =\>  
“district”})  
and same results

finally tried this:  
results = server.call(“lists”, :dbid =\>“dbid1113086003”, :getlist =\>  
“district”)

with the same results

I can run this as the base example I took it from:  
require ‘xmlrpc/client’  
require ‘pp’

server = XMLRPC::Client.new2(“[http://rpc.technorati.com/rpc/ping](http://rpc.technorati.com/rpc/ping)”)  
result = server.call(“weblogUpdates.ping”, “Copenhagen.rb”, “http://  
www.copenhagenrb.dk/”)  
pp result

And it woks fine.

What is the correct initialization and call?

## the actual xml structure that should be passed is this: lists
- - - - dbid - dbid1113086003 - getlist - district

When called from an unapproved ip it should come back with a message  
stating so.

Any ideas?

This looks right to me.

They both seem to be what we are seeing:

request = create().methodCall(method, \*args)  
puts request

end  
end

server = XMLRPC::Client.new2(“[http://websearch.ramaui.com/ramxml.php](http://websearch.ramaui.com/ramxml.php)”)  
results = server.call( “lists”, “dbid” =\> “dbid1113086003”,  
“getlist” =\> “district” )

**END**

What make you think this isn’t working?
