Subject Re: Problem calling/executing async BPEL Process
Date Mon, 01 Dec 2008 09:26:54 GMT
Hi,

of course. Sorry for not attaching it the first time. I added a service
for both ports (request and callback). I also tried it with two services
which resulted in a different error message but still didn't work.
