XML::Compile::SOAP::WSA - SOAP Web Service Addressing


   is a XML::Compile::SOAP::Extension


 # use WSA via WSDL, wsa header fields start with wsa_
 use XML::Compile::WSDL11;     # first
 use XML::Compile::SOAP::WSA;  # hooks into wsdl

 my $wsa  = XML::Compile::SOAP::WSA->new(version => '1.0');
 my $wsdl = XML::Compile::WSDL11->new(...);
 my $call = $wsdl->compileClient('some_operation');
 my ($data, $trace) = $call->(wsa_MessageID => 'xyz', %data);

 print $wsdl->operation('myop')->wsaAction;


The Web Service Addressing protocol is used to select certain service and port on a SOAP server, just like the "Host" header in HTTP.

The basic SOAP design uses the URI and the soapAction header of HTTP (in case it uses HTTP, by far the most often used transport mechanism) However, when the server is hidden behind firewalls and proxies, these fields are rewritten or replaced. This means that the definitions by the WSDL for the client can differ from the configuration of the server. This is where WSA comes into play.

When WSA is enabled, header fields are added. Automatically, the obligatory wsa_To and wsa_Action fields will be added to each request, although you may change their values with call parameters. This works both for soap clients (created with XML::Compile::SOAP) as for the soap server (created with XML::Compile::SOAP::Daemon): simply require the WSA module to get the hooks installed.

Warning: this being a very recent module, thing may not work. There is no real-life experience with the code, as yet. Please contact the author when you are succesful or discovered problems.



 -Option --Default
  version  <required>
version => '0.9'|'1.0'|MODULE

Explicitly state which version WSA needs to be produced. You may use a version number (where 0.9 is used to represent the "submission" specification). You may also use the MODULE name, which is a namespace constant, provided via ::Util. The only option is currently WSA10MODULE.
