- =head1 NAME
-
- SOAP - Library for SOAP clients and servers in Perl
-
- =head1 SYNOPSIS
-
- use SOAP;
- print "This is SOAP/Perl-$SOAP::VERSION\n";
-
-
- =head1 DESCRIPTION
-
- SOAP/Perl is a collection of Perl modules which provides a simple
- and consistent application programming interface (API) to the
- Simple Object Access Protocl (SOAP).
-
- To learn more about SOAP, visit the FAQ at:
- <URL:http://www.develop.com/soap/soapfaq.htm>
-
- This library provides tools for you to build SOAP clients and servers.
-
- The library contains modules for high-level use of SOAP, but also modules
- for lower-level use in case you need something a bit more customized.
- The library is factored so that you can
-
- SOAP/Perl uses Perl's object oriented features exclusively. There are
- no subroutines exported directly by these modules.
-
- This version of SOAP/Perl supports the SOAP 1.0 specification,
- which is an IETF internet draft. See <URL:http://www.ietf.org>
- for details.
-
- The main features of the library are:
-
- =over 3
-
- =item *
-
- Contains various reusable components (modules) that can be
- used separately or together.
-
- =item *
-
- Provides an object oriented model for serializing/deserializing and
- sending/receiving SOAP packets (lovingly referred to in some circles
- as SOAP bars). Within this framework we currently support access to SOAP
- over HTTP, but we're looking to expand to support SOAP over SMTP and
- other transports in the future.
-
- =item *
-
- Provides a fully object oriented interface.
-
- =item *
-
- Supports SOAP 1.0 spec. The current version does not yet handle arrays.
-
- =item *
-
- Supports serializing/deserializing of sophisticated object graphs
- which may have cycles (a circular queue would serialize just fine,
- for instance).
-
- =item *
-
- Provides full namespace support for SOAP 1.0, which is strongly recommended
- by the spec.
-
- =item *
-
- Implements full support for SOAP 1.0 packages, including correctly dealing
- with shared references between header and body elements.
-
- =item *
-
- Experimental support for extensibility of the serialization/deserialization
- architecture has been included; see SOAP::TypeMapper for details.
-
- =item *
-
- Supports servers using CGI or Apache+mod_perl. Tested with Apache on Linux
- as well as IIS on Windows 2000.

-
-
- =head2 The EnvelopeMaker Object
-
- SOAP::EnvelopeMaker takes as input an array of header objects and a single
- body object (currently these "objects" are simply Perl hashes, eventually
- we'll add support for blessed object references as well), and produces as
- output an XML stream.
-
- =head2 The Parser Object
-
- SOAP::Parser takes as input a string (or a file/file handle) and parses
- the content as a SOAP envelope. This results in an array of header objects
- and a single body element.
-
- To avoid coupling the SOAP serialization/deserialization code to HTTP,
- a set of loadable transports is also provided. See the following modules
- for documentation of the transport architecture:
-
- SOAP::Transport::HTTP::Client
- SOAP::Transport::HTTP::Server
- SOAP::Transport::HTTP::Apache
- SOAP::Transport::HTTP::CGI
-
- =head2 Where to Find Examples
-
- See SOAP::EnvelopeMaker for a client-side example that shows the
- serialization of a SOAP request, sending it over HTTP and receiving
- a response, and the deserialization of the response.
-
- See SOAP::Transport::HTTP::Apache for a server-side example that shows
- how to map incoming HTTP requests to method calls on your own Perl
- classes.
-
- =head1 OVERVIEW OF CLASSES AND PACKAGES
-
- This table should give you a quick overview of the classes provided by the
- library.
-
- -- High-level classes you should begin with --
-
- SOAP::EnvelopeMaker -- Serializes objects into SOAP bars
- SOAP::Parser -- Deserializes SOAP bars into objects
- SOAP::Transport -- Description of transport architecture
- SOAP::Transport::HTTP -- Description of HTTP transport
- SOAP::Transport::HTTP::Client -- Client side support for HTTP,
- using libwww-perl
- SOAP::Transport::HTTP::Server -- Server side support for HTTP,
- decoupled from web server APIs
- SOAP::Transport::HTTP::Apache -- Apache/mod_perl support
- SOAP::Transport::HTTP::CGI -- Vanilla CGI support
-
- -- Serialization architecture --
-
- SOAP::Envelope -- Low level access to SOAP serialization
- SOAP::OutputStream -- used in conjunction with SOAP::Envelope for
- Low level access to SOAP serialization
- SOAP::Packager -- Helps to implement SOAP 1.0 packages,
- used by SOAP::Envelope and SOAP::OutputStream
- SOAP::GenericHashSerializer -- Generic serializer for Perl hash references
- SOAP::GenericScalarSerializer -- Generic serializer for Perl scalars
-
- -- Deserialization architecture --
-
- SOAP::GenericInputStream.pm -- Look here if you are interested in
- extending the deserialization framework
- to be able to deserialize your own objects
- -- Miscellaneous --
-
- SOAP::TypeMapper -- An experimental extensibility point for the
- serialization architecture
- SOAP::Defs -- Constants used by the other modules
-
-
- =head1 MORE DOCUMENTATION
-
- All modules contain detailed information on the interfaces they
- provide.
-
-
- =head1 BUGS AND LIMITATIONS
-
- The serialization framework does not yet handle arrays,
- and the HTTP transport does not handle M-POST.

- =head1 ACKNOWLEDGEMENTS
-
- Keith Brown is the original and current author of this work, but
- he worked very closely with Don Box in developing a common design
- and implementation architecture (Don was building a Java implementation
- side-by-side, and Keith and Don worked together in a kind of XP style
- of programming - it was fun). GopalK at Microsoft was tremendously
- helpful in ferreting out issues in the SOAP spec. Mike Abercrombie
- at DevelopMentor (where Keith and Don work) was very supportive
- of the effort as well. Thanks Mike!
