Need a real BPEL example

[binh nguyen]

Hi everyone,
I am only a novice in BPEL and ODE. I try to find some examples of BPEL that
can run with ODE and invoke some real and concrete Web services.
I have tried all 3 examples in ODE, but all of them do not any invoke to any
real Web service. So I have also tried to develop a simple Web service,
(using Netbeans 6.1) then invoke this WS from a BPEL. But it does not work.
So I like to have some real examples to learn.
Any one can help me?
Thank you very much in advance!
Regards,
Binh.
