Dear Denis, Thank you for your reply. I did now my deploy.xml was incomplete, but Eclipse's BPEL editor did not allow me to fill it in (directly using the editor) and that is why i was feeling kind of lost.
Thank you for your example. I would also like to ask you what do you mean by having that external web service stored locally? Do you mean i have to download the WSDL for all external web services and reference them using local WSDL files? Thank you!
