If what you want to do is deploy a web service on your server, the simplest way by far is to use ColdFusion. The Cfcomponent from the ColdFusion 8 developers guide is all you need.
<cfcomponent> <cffunction name = "echoString" returnType = "string" output = "no" access = "remote"> <cfargument name = "input" type = "string"> <cfreturn #arguments.input#> </cffunction> </cfcomponent>
