uninitialized constant

I am running into issues as well. I believe this is due to the fact
that Rails stopped providing SOAP support at 2.0 and doesn't do any
longer the 'behind the scenes' thing it used to do for SOAP. I found a
post that explains how to get ActionWebService to work again with SOAP
but I lost the link. I'm also working on it so I'll let you know if I
find it.
