Invoking Siebel CRM OnDemand Web Service via BPEL

Question

I'm trying to invoke a Siebel CRM OnDemand Web Service via BPEL. Basically, the Siebel guide says to post to a url with user/pwd to get a session ID returned from a cookie. I did that using embedded java and have the session ID as a variable in my BPEL process. My problem is with now calling the Web Service to perform the action. I have a WSDL from Siebel, but the guide says to use an HTTP post with the session ID in the url and the XML in the body. How do I do that? Shouldn't the WSDL handle that when I create the Partner Link? Do I need to use more embedded Java for this or can I set up a Partner Link? I created a Partner Link and it shows the methods I want to use, but I get the following error when I try to call it because I don't know where to add the session ID:
<ErrorCode xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">SBL-ODU-01006</ErrorCode>
<ErrorMessage xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">Internal Error: Session is not available. Aborting.</ErrorMessage>
Any help would be GREATLY appreciated. Please let me know if you need more information.
THANKS!

The Siebel OnDemand web services can accept the siebel session token in the URL. Append ';jessionid={%sessionIdFromCookie%}' to the end point. Obviously this has to be done dynamically. Refer to the article called 'Making BPEL Processes Dynamic' (http://www.oracle.com/technology/pub/articles/bpel_cookbook/carey.html) pay particular attention to the 'Eliminating address dependency at run time' section.
