Web Services with C++

[Generic Usenet Account]

I am trying to do the comparative analysis of the most popular C++
open source implementations for Web Services e.g. gSOAP, EasySoap++,
WASP Server Lite for C++ etc (did I miss any prominent ones?). Does
anyone know where I can get more information? Alternatively, does
anyone have an opinion?

Thanks,
