Forum OpenACS Development: Re: TCL8.3 and TCLSOAP1.6.7
First of all, TclSOAP probably works just fine in AOLserver 4.0, exactly the same way it works in tclsh, although I haven't tried it myself and don't remember whether others have reported success or not. Which version of AOLserver are you using? Try the latest pre-release Beata of 4.0 from SourceForge.
And coincidentally, the very same day you posted your question, Vinod announced his XML-RPC package for OpenACS.
