Andrew, I had the same question about a month ago and I was given a ton of help, but most of which I couldn't use. I eventually with some digging and a little help from my local cfug I was able to pass a complex datatype to a ..NET web service and get a return.
Here is what I did: First download and install a program called Oxygen (http://www/oxygenxml.com) use this only for the WSDL analyzer that is has. Use this to build your xml soap packet to send to the .net service. Because coldfusion builds the soap in a way that the .net sees it as a variable that is not listed and empty, you have to hand craft the soap your self to send. Here is the code that builds the soap: (Be sure to copy the xml in the analyzer as a base to build from) <!---(START) Build Soap---> <cfoutput> <cfsavecontent variable='xmlSOAPcontent'> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Header/> <SOAP-ENV:Body> <CheckStoppingRule xmlns="TrialIVBuMel"> <aPatients> <cfloop from="1" to="#arrayLen(aPatients)#" index="i"><Patient> <TimeOnTest>#apatients[i].TimeOnTest#</TimeOnTest> <SubGroup>#apatients[i].SubGroup#</SubGroup> <HasDied>#apatients[i].HasDied#</HasDied> </Patient></cfloop> </aPatients> <aSubGroupContinueIndicators> <cfloop from="1" to="5" index="i"><boolean>true</boolean></cfloop> </aSubGroupContinueIndicators> <sErrors>this is the error string</sErrors> </CheckStoppingRule> </SOAP-ENV:Body> </SOAP-ENV:Envelope> </cfsavecontent> </cfoutput> <!---(END) Build Soap---> Use CFHTTP to post the soap you just created here is my code: <!---(START) Post Request ---> <cfoutput>Posting SOAP Request... <cfhttp url="#BioStatURL#" method="POST" resolveurl="YES"> <cfhttpparam type="Header" name="Content-Type" value="text/xml; charset=utf-8"> <cfhttpparam type="Header" name="POST" value="/IVBuMelWebSvc/TrialConductor.asmx HTTP/1.1"> <cfhttpparam type="Header" name="Host" value="http://biostat252.mdacc.tmc.edu"> <cfhttpparam type="Header" name="SOAPAction" value="TrialIVBuMel/CheckStoppingRule"> <cfhttpparam type="HEADER" name="Content-Length" value="#len(tostring(xmlSOAPcontent))#"> <cfhttpparam type="XML" name="CGI" value="#xmlSOAPcontent#"> </cfhttp> </cfoutput> <!---(END) Post Request ---> In closing this is the building and sending of the soap, if you want a more detailed example please send me an e-mail.
