NAME

       SOAP::WSDL::Server - WSDL based SOAP server base class

SYNOPSIS

       Don't use directly, use the SOAP::WSDL::Server::* subclasses instead.

DESCRIPTION

       SOAP::WSDL::Server basically follows the architecture sketched below (though dispatcher classes are not implemented yet)

	SOAP Request	       SOAP Response
	      | 		    ^
	      V 		    |
	 ------------------------------------------
	|	SOAP::WSDL::Server		   |
	|  --------------------------------------  |
	| | Transport Class			 | |
	| |--------------------------------------| |
	| | Deserializer       | Serializer	 | |
	| |--------------------------------------| |
	| | Dispatcher				 | |
	|  --------------------------------------  |
	 ------------------------------------------
	     | calls		     ^
	     v			     | returns
	  -------------------------------------
	 |   Handler			       |
	  -------------------------------------

       All of the components (Transport class, deserializer, dispatcher and serializer) are implemented as plugins.

       The architecture is not implemented as planned yet, but the dispatcher is currently part of SOAP::WSDL::Server, which aggregates serializer
       and deserializer, and is subclassed by transport classes (of which SOAP::WSDL::Server::CGI is the only implemented one yet).

       The dispatcher is currently based on the SOAPAction header. This does not comply to the WS-I basic profile, which declares the SOAPAction
       as optional.

       The final dispatcher will be based on wire signatures (i.e. the classes of the deserialized messages).

       A hash-based dispatcher could be implemented by examining the top level hash keys.

EXCEPTION HANDLING

   Builtin exceptions
       SOAP::WSDL::Server handles the following errors itself:

       In case of errors, a SOAP Fault containing an appropriate error message is returned.

       o   XML parsing errors

       o   Configuration errors

   Throwing exceptions
       The proper way to throw a exception is just to die - SOAP::WSDL::Server::CGI catches the exception and sends a SOAP Fault back to the
       client.

       If you want more control over the SOAP Fault sent to the client, you can die with a SOAP::WSDL::SOAP::Fault11 object - or just let the
       SOAP::Server's deserializer create one for you:

	my $soap = MyServer::SomeService->new();

	die $soap->get_deserializer()->generate_fault({
	   code => 'SOAP-ENV:Server',
	   role => 'urn:localhost',
	   message => "The error message to pas back",
	   detail => "Some details on the error",
	});

       You may use any other object as exception, provided it has a serialize() method which returns the object's XML representation.

   Subclassing
       To write a transport-specific SOAP Server, you should subclass SOAP::WSDL::Server.

       See the "SOAP::WSDL::Server::*" modules for examples.

       A SOAP Server must call the following method to actually handle the request:

       handle

       Handles the SOAP request.

       Returns the response message as XML.

       Expects a "HTTP::Request" object as only parameter.

       You may use any other object as parameter, as long as it implements the following methods:

       o   header

	   Called as header('SOAPAction'). Must return the corresponding HTTP header.

       o   content

	   Returns the request message
