[Zope] Working example of SOAP

Hi all, I need to implement a SOAP interface for our Zope website. I was trying to follow the example at http://www.zopemag.com/Issue005/Section_Articles/article_SOAPandZope.htm l , which uses ZSI and guylux's patch for Zpublisher but could not get it to work. Can somebody point me to a working example of Zope and SOAP using ZSI or alternatives. The version of Zope used is 2.8.7. Many thanks, Vimal
