This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I studied the sample use case and solution in Humphrey Sheil's book. The use case mentioned that the exhange will be exposed as a web service. But, in the solution there is no mention of web service. It looked to me that this solution will not have even have JSPs and only web service points. I am totally confused.
