=head1 NAME

SOAP::WSDL::Server::Simple - CGI based SOAP server for HTTP::Server::Simple

=head1 SYNOPSIS

 package TestServer;
 use base qw(HTTP::Server::Simple::CGI);
 use MyServer::TestService::TestPort;

 sub handle_request {
     my ($self, $cgi) = @_;
     my $server = MyServer::TestService::TestPort->new({
         dispatch_to => 'main',
         transport_class => 'SOAP::WSDL::Server::Simple',
     });
     $server->handle($cgi);
 }

 my $httpd = __PACKAGE__->new();
 $httpd->run();

=head1 USAGE

To use SOAP::WSDL::Server::Simple efficiently, you should first create a server
interface using L<wsdl2perl.pl|wsdl2perl.pl>.

SOAP::WSDL::Server::Simple dispatches all calls to appropriately named methods in the
class or object set via C<dispatch_to>.

See the generated server class on details.

=head1 DESCRIPTION

Lightweight SOAP server for use with HTTP::Server::Simple, mainly designed
for testing purposes. It allows to set up a simple SOAP server without having
to configure CGI or mod_perl stuff.

SOAP::WSDL::Server::Simple is not recommended for production use.

=head1 METHODS
