Thanks for the quick reply. It seems I have made some rather silly errors in my client code: 1) I was assigning the newSession to a local session variable instead of my class member (unintentionally) 2) I didn't realize that the "url" argument to open->(URL) was an actual qpid Url class rather than a URL string. Should pay closer attention to the header files... That said, I would have never had a clue as to the 0.10 URL format without your tip. I have been looking around for some documentation on that format, but I haven't found any on the web as of yet -- some proposals, but nothing solid. Could you possibly point me where I could find decisive documentation on the 0.10 url format beyond just "amqp:tcp:host:port"?
