I still can't get this to work. I'm suspect it may have something to do with me
not having a package-info.java class in my classpath.
I Don't know that this does. I just noticed that the sample has one and I don't
and the fact that it says something about bindings and schema which is what
line 213 is looking for.
But when I add a package-info.java I get a exception trying to publish my rest
interface -
INFO: Creating Service

Which matches the package name of my Service -

Subject: Re: REST & XPath
OK I spent some time digging into this - you may also want to see my post to
Willem.
Your test case works for me. I have to ask though - are you sticking an xpath
expression in the URL? If so, are you escaping it? If not, the additional "/"s
in the URL are likely to confuse the URI parser inside CXF.
As I understand URI templates, "/" is a sacred character and you can't have an
unescaped "/" inside data which you want mapped to your method parameter.
