[snichols] I'm working on a Tcl client to integrate to a web service. I have an example of how the SOAP envelope should look. It is using two complex data types (WebUser and Authentication). I'd prefer to use Tcl SOAP then have to code the XML using tDOM and HTTP, which I will do if necessary. Here's my Tcl code that generates a SOAP request envelope that's close to the working SOAP envelope, but not good enough for the web service (there are some extra XML attributes, etc that are needed): package require SOAP package require rpcvar namespace import -force rpcvar::typedef typedef { Username DATA Password DATA Nonce DATA Created DATA RemoteUser DATA RemoteClient DATA RemoteAddress DATA EnvironmentalData DATA SessionID DATA } authentication typedef { Authentication authentication ApplicationType DATA RequestID DATA WebUserID DATA WebUserName DATA PlanID DATA EmployerID DATA MemberID DATA EntityType MEMBER EntityReferenceNumber DATA Password DATA EncryptionMethod PLAINTEXT InputMethodEditor TELEPHONE } webUser SOAP::create Test -proxy "http://localhost/superSOAP/webcontrol.asmx" \ -action "http://www.atune.biz/web/services/WC/2006-01/isWebUserAuthenticated" \ -uri "http://www.atune.biz/web/services/WC/2006-01" \ -params {WebUser webUser} When the soap method, isWebUserAuthenticated, is called it generates this as the SOAP request : IVRUSER newPassword TESTER SomeCompany 127.0.0.1 MOL 11111 RS -1 -1 MEMBER 0 5555 PLAINTEXT TELEPHONE Its very close, but I need the SOAP above envelope to look like this working version (both are very close): IVRUSER newPassword 20060309T080101 TESTER SomeCompany 127.0.0.1 MOL 157014233 RS -1 -1 MEMBER 0 5555 PLAINTEXT TELEPHONE Any ideas what I need to change in my TclSOAP command calls to make the SOAP envelope look like the latter XML above? Its currently generating the first XML. I notice a couple of things different: The latter has an Enabled="1" attribute and its not using the /ns: namespace. The latter envelop works and returns a result the first request returns errors. The other thing thats differnt is the second version using simpler looking tags like soap:Evelope and soap:Body. Thanks in advance. snichols.
