Hi Santhosh This kind of error usually means that the service that the BPEL is calling has returned an error of some kind. The error handling in impl.bpel is not very good at the moment and needs improvement hence this rather opaque output.
It seems to be going wrong on the call out to the sayHelloPartnerLink. Can you check that that is properly wired in the SCA composite. If it is are you able to look at the HTTP requests going between the BPEL and this partner? That should give you a clue about what is going on. Regards Simon
