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.
First of all i would like to congratulate you for promoting "SOA using web services", and giving us a chance to win a copy of it.
I wanted to clarify some of my doubts related to SOA:
1) how is web services related to SOA, and since web services is a very old concept used by the indusdry while SOA is a new concept, so how do you think web services will be able to solve out SOA purposes.
WS are one way to implement a SOA; arguably the only viable way right now that has sufficient infrastructure in place for complex environments. The relationship between WS and SOA was discussed recently in this thread.
