Consuming a webservice with jsessionid in URL

I`m working on a SAP project, where i have to call a non-sap service with jsessionid in binding url. I already generated a proxy class out of the wsdl and defined a logical port with my URL. In my case it should be dynamic like: {host}/service/foo/binding;jsessionid={xxx} but its static like: {host}/service/foo/binding

How can i achieve that session handling?

EDIT: The problem here is, its not only for authentification its also for load balancing. The jsessionid MUST be submitted via URL rewriting. Any ideas?

You should be able to configure this with the soamanager transaction:

• Go to the service configuration screen and select your consumer proxy
• Edit the existing, or create a new logical port
• Go to the transport settings tab and change the URL access path

Once saved, you can find the logical port as a destination in transaction SM59. It's one of the generated ones in the external HTTP connections tree.

Providing a value for the parameter will probably require a modification of the SAP software though. The system uses the cl_http_client=>create_by_destination method to obtain a client object to perform the http call, so maybe you can implement some custom code there.
