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.
I am browsing Pet Store 1.3.1 from Sun. Any body can give me a reason why they use one service locator for web tier and the other for Business/EJB tier. The only difference I noticed is the web tier service locator "cache" the references.

Could it be because of (some of) the following: a) they wanted to demonstrate two different ways of implementing the service locator pattern. b) they didn't have the time/interest to write a configurable service locator (cache on/off) I'm just guessing here...
