For your question I think the steps that you used to not using WebServices, but for Web applications that will use the browser to do single sign-on.
This infinite redirect error can be corrected using Agent 3.0 for JBoss, but as I said these steps are for web applications, but for webservices.
I also am looking for a way to make the security of web services with opensso! If you have any tips or know of something would be good.
