BizTalk WCF and Soap Action

i'm calling a WCF service using BizTalk 2009 as intermediate endpoint, now i changed the wsdl of the service being called by biztalk (i changed the soap action attributes in the wsdl's binding section开发者_JAVA技巧), now when i call the service via-biz talk exposed WS it inform's me about an interface mismatch (regarding the Action attribute), how can i solve this ?

Thanks in advance

If you've just changed the SOAP Action, then you can change this in BizTalk on the send port (Admin Console, Right Click on the Port, Configure, and change the Action under the General tab at the bottom). But if you've changed schemas, added new operations etc, you should regenerate everthing again as per Maxine's comment.
