statefull session between JAVA and SAP

Hi all,

i want to build a statefull session between a JAVA-Application and a SAP WebAs 6.2.

I heard, it's not possible with RFMs, but with Business Objects, but I still didn't find a way to instantiate a BO by the JAVA Application.

I only have access to the BAPIs, but how can I influence the behavior of the BO by the BAPIs.

Does anybody have information about this?

Kind regards,

Christian Lorenz
