Using SOAP Headers in Pipeline Components
To access the SOAP header context properties in pipeline components, you use a combination of the context property name and target namespace as discussed in Using SOAP Headers in Orchestrations.
The following code example sets the request SOAP header in a send pipeline component for a property name OrigDest:
public IBaseMessage Execute(IPipelineContext pc, IBaseMessage inmsg)
{
try
{
string stringVar = "<?xml version=\"1.0\"?>
<OrigDest xmlns=\"http://SOAPHeaderSchemas.OrigDestSOAPHeader\">
<Origination>Home</Origination>
<Destination>Work</Destination>
</OrigDest>";
inmsg.Context.Write("OrigDest","http://schemas.microsoft.com/BizTalk/2003/SOAPHeader", stringVar);
}
catch (Exception ex)
{
throw new Exception("Pipeline component exception - " + ex.Message);
}
return inmsg;
}
For more information about pipeline components, see Developing Custom Pipeline Components.
Note
When you consume (call) Web services from an orchestration, the SOAP adapter only supports pass-through style receive and send pipelines. You can use a custom pipeline, but it cannot contain components that modify the body parts of the message. These components include the XML Assembler, XML Disassembler, and XML Validator components.
