There are plenty of articles around that describe the differences between EJB 2 and 3, but does the book go into any detail about this with regards to converting applications from EJB 2.x to 3.0?

If so, does it go into any architectural depth, such as "the DTO pattern (and other patterns) is/isn't necessary in EJB 3"?

Thanks.

Jon has answered similar question on migration before, you can look it up on the forum. Migration

You might find one of the earlier postings on my blog that talks about DTO

Thanks for the reply, your posting about DTOs makes sense. Do you cover any details about other patterns in the book (or your blog)?

I'm familiar with J2EE 1.4 apps, and am really interested in which patterns don't make sense when using EJB 3.
 
Don't get me started about those stupid light bulbs.
