Looking for a list of available SOAP Server implementations

Greetings.

I am evaluating SOAP server options for a customer of ours.  gSOAP and
Axis are both viable but our customer wants to know about other options,
in particular commercial options.

The target space is C/C++ on Linux, possibly embedded Linux in the future.
 Can any one point me to an SOAP Server FAQ or a general list of available
SOAP Server implementations?

Thanks in advance.
