This is probably a dumb question but:
I’m trying to call a third party web service from BizTalk 2006. The service returns book title information and has a signature:
GetTitle(TitleId As String, ByRef ErrText As string ) as TitleInfo
The web service works fine when tested directly from a VB.net assembly.
Unfortunately the service does not expose schema types.
I have created:
– a schema project that imports the web reference.
This gives me a GetTitle_request and a GetTitle_response Multi-Part message type.
– a second project containing a bare bones orchestration to test this.
The orchestration includes:
– A TitleRequest_Message to instance the GetTitle_request.
– a message constructor to construct a TitleRequest_Message.
– a Message Assigment to set the TitleId element (hard coded to \”10\”)
– a send process
– a port bound directly to the web service using SOAP transport to the correct URI
– a receive process bound to the Response
– a send process to dump the response to file.
As a new user, I would expect that to be enough to create a valid SOAP request to call the GetTitle method. But the packet sent to the web service is a bare bones XML packet consisting of only an XML header followed by the literal text <string>10</string>. No SOAP method or TitleId element. What am I missing?

I ran into something similar a few months ago.
If I remember correctly, at least one of the input to the web service had to come from a BizTalk Message. Must have something to do with constructing the request message.
Try creating a distinguished field and using that as your input to the web service rather than hard coding it.
Also, make sure you are constructing the multi-part message BizTalk created for you when you added the web reference. It should have a part for each input parameter. That is what you want to set.
Not sure it that will work – but I guess it’s worth a try.

I am experiencing a similar situation. Could you please share the solution if you have found one.

first I wouldrecommend you strip the problem down to something very simple if you can – a single call out ot a web service from a simple orchestration. Add a web reference and use the “specify now” option.
I don’t see any reason why you can’t call out to simple web services with simple types – so can you share your web service signature?
