The seam community site went live exactly one month ago, and already boasts more than 1000 registered members, with twenty-something people signing up every day. The new forum is buzzing, and we're starting to get lots of useful information up on the wiki.
Several times, I've encountered the following view:
Stephan Schmidt says that people don’t get the difference between business and UI logic:
To celebrate the new release of JBoss Tools, I'm going to walk through some of the features of JBoss Tools that are interesting to Seam developers.
So, I've been following this discussion with interest. I'm still confused. All I'm really getting out of the comments on this thread is: there's some other objects in the system that aren't DAOs or entities
. But I knew that already. Clearly, I need to actually read the damn book for myself. Still, it really doesn't fill me with confidence that people who /have/ read the book don't seem to be able to explain (in words or code) the Repository notion coherently. And it looks like everyone has their own private take on what exactly a Repository is all about. This gives me a hint that the idea is not especially well-defined.
Kinda tangentially related to this discussion, I'm often asked whether I believe in rich
domain models or anemic
domain models. I guess I'm pretty much ignorant as to what these terms really mean, since I've never seen a proper definition of either term.
