This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
reading HFS&JSP, page 254 says (bottom box): "You do not configure session binding listeners in the DD". The errata says that should instead say: "You do not configure session binding listeners or session activation listeners in the DD".
But then, on page 261, there is a Dog class that implements both HttpSessionBindingListener and HttpSessionActivationListener. In the bottom of the page, the listener IS CONFIGURED in the DD, and the box right of it says that is MUST be configured because of the Activation listener. The errata doesn't say anything about this page.
So, after all, HttpSessionActivationListener's are configured or not in the DD?
I'll probably never use that, but it's in the exam...
