SOAP

Simple Object Access Protocol


This page deals with XML RPC and - more specifically - SOAP.

SOAP is quickly emerging as an important standard for distributed applications.

SOAP should be supported by Squeak. The objective of this page is therefore to collect information which is or might be useful for implementors and those Squeakers who would like to use SOAP.

The main code for SOAP was written by Camp Smalltalk people:
http://wiki.cs.uiuc.edu/CampSmalltalk/SOAP+Smalltalk+Reference+Implementation
This should be the base for further developments.

See XML: Parsers for a Squeak-port of the XML framework which is the foundation for the Camp Smalltalk SOAP code
See also the page about "XML and DOM support for Squeak" XML/DOM in (on?) this Swiki.
A class named 'XmlRpcModule' exists in category 'Comanche-XML RPC' of the Comanche Squeak webserver but the class is not used in the change set. There are even methods named 'asSoapMessage' and 'asSoapDictionary' in classes 'XMLdocument' and 'XMLnode' respectively. Does anyone use any of these?

Bolot Kerimbaev wrote on July 25, 2000 to the Squeak list:

"A simple (see notice below) implementation is included with Comanche
(web app dev framework):
http://comanche.swiki.net

"Notice: the XML-RPC and SOAP were started, but are not entirely
complete. The obvious big thing that's missing is a tighter
integration with Squeak, although some starting code is there.
Oh, and this includes my own XML parser - there are a few dozen
more out there in the Squeakville.

"I'm planning to take this implementation further to completion this
Fall, as it will be an essential component of another project.
I might completely discard my code in favor of Camp Smalltalk work,
since they've turned out tons of useful stuff (still have to dig
through for relevant treasures)."
Work is also being done for an Object Request Broker Fly-By-Wire - A Squeak ORB #2.
