xml-rpc calling question

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...)
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/...)
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:
<methodCall>
<methodName>lists</methodName>
-
<params>
-
<param>
-
<value>
-
<struct>
-
<member>
<name>dbid</name>
-
<value>
<string>dbid1113086003</string>
</value>
</member>
-
<member>
<name>getlist</name>
-
<value>
<string>district</string>
</value>
</member>
</struct>
</value>
</param>
</params>
</methodCall>

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:

$ ruby xtest.rb

require "xmlrpc/client"

class XMLRPC::Client
def call2(method, *args)
request = create().methodCall(method, *args)
puts request
data = do_rpc(request, false)
parser().parseMethodResponse(data)
end
end

server = XMLRPC::Client.new2("http://websearch.ramaui.com/ramxml...)
results = server.call( "lists", "dbid" => "dbid1113086003",
"getlist" => "district" )

__END__

What make you think this isn't working?
