This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
SuD needs to interact with an internal application (which is also written in Java). What is the best way to communicate with it when no other details are provided? Since it's synchornous call, I believe JCA or Web Service could be used. But both (or any) approaches would require some changes in this existing application, which is outside SuD.
Shall I just assume any of these and go ahead? Any thoughts?
