accessing soap:header in biztalk for use in exported bpel

Hey all,

I’m currently struggling with Soap-Headers in my BizTalk 2006 project. I have a webservice, its WSDL clearly demands a SoapHeader \”myGuid\”.

1. BizTalk doesn’t provide me with a property for an invocation message, myMessage.myGuid is not working.
2. I defined the SOAP header by using context propertires, achieved to access the property in the Expression Editor

Now I have a big question: I want to export this process to bpel, but when I build the solution, I get the Error \”reference to a message context property \”myProject.myGuid\” is not permitted under BPEL4WS compliance.

Does anyone know, how I could achieve the setting of a soap:header value while staying bpel4ws compliant?

Any help greatly appreciated,

Yorck
