Hi.... I know that the purpose of the user mailist is to ask for hints of how to solve a problem o what one is doing wrong, but I'd like to ask for instructions of how to solve my problem.
I have red a lot of thread from this list that where having quite the same problem involving the selection:failure error, but at the end users claim to have solved their problem without even posting the solution. I also have red ODE FAQ (as Tammo van Lessen always urge to do) and I understand the problem, but I just don know how to solve it. I know I'm quite newbie to XML, WSDL and BPEL, but in this case I've tried an red a lot, but it just seem that I've ran out of ideas. So please can somebody tell me what It must be done? .... I really need it. 2012/11/13 Dago Pacheco <[email protected]>: > Hi everybody.... I'd like you to help me out a little bit. > > I'm building a test BPEL process which invoke a REST webservice.
