BT2004 + Web Services + Array types = Problem
|
|
|
| I'm trying to use BT2004 with some pre-existing web
services. When I try to add the Web Reference I get this
error: "Could not generate BizTalk files. "An 'xxx'
operation parameter or return type is an Array. Array
types are not supported." Why is this a problem, when is
it going to be fixed, and are there any good workarounds?

John,
This is a known issue. I assume you are trying to call the web service from
an orchestration.
In that case, as a workaround, you can write a .NET function that makes the
web service call and return the data.
Compile this function into an assembly and call it from your orchestration.

Gilles,
I am also facing the same problem. So as you adviced I am creating another ASP.NET WebService in VS.NET which will call WSDL files (created from Microsoft Soap Toolkit) through web reference. In my VB6.0 components, I am accepting IXMLNodeList and also returning IXMLNodeList.
But when I try to call the function from web reference (wsdl) and pass System.Xml.XmlDocument.ChildNodes, I got error "You must implement the Add(System.Object) method on System.Xml.XmlNodeList because it inherits from IEnumerable."
This is what I am doing in ASP.NET Web Service:
System.Xml.XmlDocument oXml = new System.Xml.XmlDocument();
System.Object obj;
Enterprise.E2 webService = new Enterprise.E2(); // this is from webReference, which i created from wsdl files and these wsdl files are created from SOAP Toolkit.
oXml.Load(@"C:\Tutorial\Test.xml");
obj = webService.FunctionName(oXml.ChildNodes); 'Error comes on this line
Error Description is :You must implement the Add(System.Object) method on System.Xml.XmlNodeList because it inherits from IEnumerable.
Please help me out here, what should I do now.
Thanks in advance.
