Explanation.md

###Intro Tests were run against localhost. The SOAP server is Fuse ESB (Apache Servicemix) with the 'cxf-osgi' example that provides a dirt simple HelloWorld. The CXF route utilizes the strategy outlined here: https://gist.github.com/1289254 and I've appended my dao code for the hell of it. The not showing bits are the generated sources from CXF

###Versions JRuby was 1.6.3 w/ --1.9. MRI Ruby was 1.9.2-p290. REE ree-1.8.7-2011.03. Rubinius was rbx-head via rvm. It choked on the threaded text, and macruby would run neither test. Apache CXF was 2.3.7.

####Details I ran everything on my Macbook Pro, 2.4GHz Core i5 w/8GB of RAM.

###Issues I continually ran into issues with Savon.

1. I would pretty consistently get what seemed to be threading issues with Nokogiri. This seemed to get alleviated by removing the WSDL parse step and just setting the namespace/endpoint directly, which as a caveat, is the recommended performant way according to the Savon docs. I used version 0.9.7 for my tests.

2. httpi which Savon uses throws errors when threaded.

 NameError: uninitialized constant HTTPClient

I'm not sure what the root semantics causing this is, but the lib/httpi/adapter/httpclient.rb file references the httpclient class without requiring it. I suspect it works generally because there's an assumption that whatever has required the adapter has required httpclient. When I added the require statement to the adapter, this seemed to fix the issue.

HelloDao.java

package com.vetstreet;

import javax.annotation.Resource;

import org.apache.servicemix.examples.cxf.HelloWorld;
import org.apache.servicemix.examples.cxf.SayHi;

public class HelloDao {
	
	@Resource
	HelloWorld helloService;

	public String sayHi(String message)
	{
		SayHi hi = new SayHi();
		hi.setArg0(message);
		return helloService.sayHi(hi).getReturn();
	}
	
}
