Dear dvohra16,
Thank you for the great book you're recommended. It's really a powerful tool that makes things much better for me.
I've noticed that you're the author of this book. I'm really honered to discuss with the problems I have and
I'm so lucky to get your responses for my questions.
My current question is based on this book. How do I orchestrate a web service that inserts into an oracle database table and a web service that reads
the contents of that table?
In other words, the first web service inserts some values into a table and the second should read these values.
So, how does BPEL orchestrate these web service such that the output of the first one is the input of the second?
Your assistance is truly appreciated.
Thank you for your time.
