There are two main options for creating a SOAP service using SOAP WSDL:
1) SOAP::WSDL::Server::CGI
See example/server/hello_simple.pl in the SOAP::WSDL source
2) SOAP::WSDL::Server::Mod_Perl2
Useful only if you'll be running your SOAP server under an Apache 2.x instance using mod_perl. See the perldoc for SOAP::WSDL::Server::Mod_Perl2 for details on use.
