The [TclSOAP] package has been expanded to cover XML-RPC as an RPC protocol as well as [SOAP]. As the two protocols are pretty much identical this should come as no surprise. There is support for providing SOAP and XML-RPC services from tclhttpd and constructing clients by binding tcl procedures to the [RPC] provided method. See http://tclsoap.sourceforge.net/ for the details.

The XML-RPC subsection of the TclSOAP page is headed by a big banner saying "This code has been superceeded [[sic]] as of version 1.6"  The question is, superseded how, and by what?

[PT] 29-May-2003: That section covers XML-RPC as a ''service''. Writing client code is simple - but undocumented now that I check. However, it's pretty much the same as SOAP but with less variable types. The validator1.tcl script in the tclsoap samples directory implements a client for the Userland XML-RPC interperability tests. This should provide some help concerning the use of this package.

[DcK] 2013-01-19. Here a sample to write a XML-RPC client with TCLSoap. It interacts to Bugzilla.

[SC] Just noticed the Wiki RPC interface definition [http://www.ecyrd.com/JSPWiki/Wiki.jsp?page=WikiRPCInterface]
implemented in a few wiki tools.

[Jacob Levy] Mar 7, 2004: If anyone figures out how to use XML-RPC services with tclhttpd then please add an example here. I need this to work, dammit :) -- I might end up figuring it out for myself, if so I'll update here.

[Scott Gamon] - If someone passing by here still wants to know how to provide XML-RPC services with tclhttpd, I wrote a page of docs on the subject[http://www.gamon.org//Profession/TCL/TCL-TclHttpdWebServices.htm]. dead link -> [http://web.archive.org/web/20051024042325/www.gamon.org/Profession/TCL/TCL-TclHttpdWebServices.htm]

[Jacob Levy] Mar 8, 2004: Scott thanks for that page, very helpful. In the meantime [Pat Thoyts] and myself have spent a bunch of time unifying XML-RPC and SOAP support for tclhttpd so that in an upcoming release XML-RPC will work again under tclhttpd with the base tclsoap distribution. We took many ideas embodied in the cgi-bin support and in Scott's excellent work, and incorporated them into the tclsoap package. Pat is the one responsible for a new release, when it's ready I'm sure he'll release it.
