TclSOAP
http://tclsoap.sf.net
It supports SOAP and XMLRPC.
It allows for plug in transports and has a CGI mode. So there must be a way to work it into using the AOL HTTP facilities.
It was on my list of things to do. I hacked a way to make it work. It requires nsexpat and nstcldom packages, which I believe you can get from the AOLserver sourceforge site. If not I have copies here somewhere that work.
My goal was to write an XML layer to allow TclSOAP to work unmodified with tDOM xml parser running inside AOLserver so that we wouldn't have 2 or 3 XML parsers running for OPenACS. Another option is to fix the minimal XML parsing in OpenACS to use nstcldom.
