Getting all of it to work: War, OSGI, Spring Beans, Maven - maven

Question

Trying to deploy a war with a bean file in a Fuse Servicemix (version 4.3.1). I'm using maven to build my war. I can't seem to get this to work. Can anyone provide a website that can tell me how to do this?
This website tells me what to put in the web.xml file but doesn't explain the rest.
http://fusesource.com/docs/esbent/7.0/esb_deploy_osgi/BuildWar-Spring.html.
I've tried several solutions and methods over the course of 19 days. Everyone seems to skin this cat differently but none of them work for me.
fat war (SOLVED):
See answer below
skinny war:
Seems impossible in osgi. Need to manually import too many packages.
This link appears to solve it but seems there a lot of nasty side effects.

Answer 1

You need to add the Spring OSGi ContextLoaderListener to your web.xml otherwise it doesn't work. You'll also need dependencies to Spring-DM 1.2.1.
Take a look at Pax Web Spring sample and especially the web.xml in it. It's a working example on how to use Spring in Karaf / Fuse-ServiceMix ...
I guess I pointed you to the wrong sample. You need t use the following.
contextClass
org.springframework.osgi.web.context.support.OsgiBundleXmlWebApplicationContext

Answer 2

Fat War solution
This is the minimum viable solution that worked for me. I played around trying to remove things and it broke as soon as I did, often without even posting an error message.
