Java/Rails XML-RPC communication

Hi, I'm having some issues with Java/Rails XML-RPC communication. Has anyone tried this?

For testing, I'm just trying to make a 0-argument request, and receive an integer response. I know that the rails app works fine - I have a number of working controllers on it already.

--Java Client-- For the Java client, I'm using the Apache XML-RPC client (ws-xmlrpc - Apache XML-RPC). The code is:

  XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();   config.setServerURL(new URL("http://pdbrs3.sdsc.edu/ContactMap/ce_mc_alignment/request"\));   XmlRpcClient client = new XmlRpcClient();   client.setConfig(config);   Integer result = (Integer) client.execute("blah", new Object{});   System.out.print(result);

--Rails-- For Rails, I did "script/generate webservice ce_mc_alignment request". This generated a controller and a web service api. I modified them as follows:

class CeMcAlignmentController < ApplicationController   wsdl_service_name 'CeMcAlignment'

  def request     154   end end

class CeMcAlignmentApi < ActionWebService::API::Base   api_method :request, :returns => [{:jobID => :int}] end

--Server configuration-- I use Lighttpd, with multiple Rails apps. The /ContactMap/ in the url above reflects this.

--Error-- When I run the Java code, I get a server response of 500. The development.log file says:

Processing Base#request (for 69.241.224.210 at 2006-08-25 19:10:40) [POST]   Session ID: 587399584c8e56b65a4bfbc85e18b9ab   Parameters: {"action"=>"request", "controller"=>"ce_mc_alignment", "methodCall"=>{"methodName"=>"blah", "params"=>nil}}
